SD303EVK / SD307EVK National Semiconductor EVK User Manual LMH0303 / LMH0307 Evaluation Board User Guide February 3, 2010 Overview The SD303/SD307 Evaluation Kit (EVK) enables evaluation of the LMH0303 3G/HD/SD SDI Cable Driver with Cable Detect or the LMH0307 3G/HD/SD SDI Dual Cable Driver with Cable Detect. A graphical user interface allows managing the SMBus registers of the LMH0303 or LMH0307 device. Evaluation Kit (SD303EVK / SD307EVK) Contents The EVK contains the following parts: • SD303/SD307 EVK board assembly with either the LMH0303 or LMH0307 cable driver • USB cable • SD303/SD307 EVK User Guide Evaluation Board Description The evaluation board comes in two versions, depending on the cable driver installed: 1) SD303 with the LMH0303 cable driver 2) SD307 with the LMH0307 dual cable driver The two cable drivers share the same evaluation board (SD303/SD307). The SD303/SD307 evaluation board silk screen shows the LMH0307 pin name terminology. Table 1 shows the pin name differences between the LMH0307 ¯¯¯¯ . The LMH0307 has that same output and LMH0303. The LMH0303 has a single output channel, SDO/SDO ¯¯¯¯¯ . In addition, the LMH0307 adds a second output channel: SDO1/SDO1 ¯¯¯¯¯ . channel and refers to it as SDO0/SDO0 Table 1.

SD303/SD307 Evaluation Board SD303/SD307 EVK User Guide Rev 1.2 2 of 27 © 2010, National Semiconductor Corp. SDI Input and SDO Output The SDI input connectors (J1 and J2) are 50Ω SMA connectors. The SD303/SD307 is initially configured for 100Ω differential input. To configure the SD303/SD307 for 50Ω single-ended input, remove R28 and place 49.9Ω 0402 resistors in R9 and R10. When using only one input, the other input should be terminated with a 50Ω SMA termination. The SDO output connectors (J3 and J4 for the SD303; and J3, J4, J5, and J6 for the dual output SD307) are 75Ω BNC connectors. When using only one side of an output pair, the other side should be terminated with a 75Ω BNC termination. For example, when only using SDO0 on the LMH0307, ¯¯¯¯¯ SDO0 should be terminated with a 75Ω BNC termination. DC Power Connectors and USB Connector The red and black binding posts (J8 and J9) provide power for the LMH0303/LMH0307 device, and the USB connection provides power for the remaining board functions, including the microcontroller and the LEDs. For proper operation, the SD303/SD307 should first be powered with a DC input voltage (between J8 and J9) of 3.3V ± 5% (3.6V maximum), and then the USB cable should be connected between the evaluation board and the PC. The POWER LED will flash Red while the board is powered from the 3.3 VDC supply alone, and then change to solid Green once the USB cable is connected to the PC. The POWER LED will remain Green as long as the board is powered correctly. JP1 – LMH0303/LMH0307 Jumper Connection to Microcontroller A jumper block should be placed on JP1 to connect the LMH0303/LMH0307 pins to the microcontroller. The ALP software will not function correctly if this jumper block is not in place. Separate jumpers may be used, but they ¯¯¯¯ (pins 5-6), ENABLE (pins 7-8), SDA (pins 9-10), SCL must be placed to connect the following pins of JP1: RSTI ¯¯¯¯¯¯ ¯¯¯¯¯ (pins 17-18). This jumper block (or individual (pins 11-12), SD/HD (pins 13-14), FAULT (pins 15-16), and RSTO jumpers) may be removed to control the LMH0303/LMH0307 pins externally, but then the microcontroller will no longer be able to communicate with the cable driver. Controls and Indicators ENABLE The ENABLE push button switch controls ENABLE, and the ENABLE LED shows its state. The ENABLE LED is Green when the cable driver is enabled (ENABLE = 1), and Red when the cable driver is disabled (ENABLE = 0). When the cable driver is disabled, it enters a deep power down mode, and Termination Fault detection and ¯¯¯¯ LOS detection no longer function. If the LOSEN register bit (bit 4 of register 05h) is set, then the cable driver can be disabled with ¯¯¯¯ LOS detection still functioning. With LOSEN set, ¯¯¯¯ LOS is combined with the ENABLE functionality. In this mode, disabling the device by pushing the ENABLE switch will still power down the device completely (including powering down Termination Fault detection and ¯¯¯¯ LOS detection), but if ENABLE is left active and the signal is removed from the input, the device will power down with the ¯¯¯¯ LOS detection still functioning. When the input signal is reapplied, the device will power back on. SD/HD The SD/HD push button switch controls SD/HD, and the SD/HD LED shows its state. The SD/HD LED is Green when the cable driver is configured for HD/3G edge rates (SD/HD = 0), and Red when the cable driver is configured for SD edge rates (SD/HD = 1). The default setting for the SD/HD LED is Green for HD/3G edge rates. SD303/SD307 EVK User Guide Rev 1.2 3 of 27 © 2010, National Semiconductor Corp. ¯¯¯¯ RSTI ¯¯¯¯ push button switch controls RSTI ¯¯¯¯ , and the RSTI ¯¯¯¯ LED shows its state. RSTI ¯¯¯¯ is used to reset the cable The RSTI ¯¯¯¯ LED is Green during normal operation (RSTI ¯¯¯¯ = 1), and Red when driver to its default register settings. The RSTI ¯¯¯¯ = 0). To reset the device, the RSTI ¯¯¯¯ switch must be pushed twice to fully the cable driver is held in reset (RSTI ¯¯¯¯ = 0), and again to resume normal operation (RSTI ¯¯¯¯ = 1) toggle reset: once to put the device in reset mode (RSTI with the default register settings. ¯¯¯¯¯ RSTO ¯¯¯¯¯ LED shows the state of RSTO ¯¯¯¯¯ . The RSTO ¯¯¯¯¯ LED is normally Red to indicate RSTO ¯¯¯¯¯ = 0. RSTO ¯¯¯¯¯ is the The RSTO reset output used when daisy chaining multiple cable drivers on the same SMBus. After writing a new device ¯¯¯¯¯ LED changes to Green to indicate RSTO ¯¯¯¯¯ = 1. RSTO ¯¯¯¯¯ remains address to register 00h (the ID register), the RSTO ¯¯¯¯ . high until the device is reset with RSTI Termination Faults (TFxx) The Termination Fault LEDs show the state of the Termination Faults on the cable driver outputs. The Termination Fault LEDs are Green to indicate proper termination, Red to indicate improper or missing termination, and off to indicate the Termination Faults are not valid under the current cable driver conditions. The cable driver must be enabled and must have a valid input signal in order to properly detect cable termination on the output. If no signal is detected and the ¯¯¯¯ LOS LED is Red, then the Termination Fault detectors (TF1P, TF1N, TF0P, and TF0N for the LMH0307) cannot determine the state of the output termination and the LEDs will be off. When a valid input signal is applied, the Termination Fault detectors will show the correct state of their termination. If the cable driver is disabled or if the output channel is powered down, the Termination Fault LEDs will be off. ¯¯¯¯ LOS The ¯¯¯¯ LOS LED shows the status of the input signal detector. The ¯¯¯¯ LOS LED is Green to indicate a valid input ¯¯¯¯ = 1), and Red when no signal is detected (LOS ¯¯¯¯ = 0). When the cable driver is disabled (ENABLE = 0), signal (LOS the ¯¯¯¯ LOS detection is disabled as well and the ¯¯¯¯ LOS LED will be Red to indicate no signal can be detected. If the ¯¯¯¯ LOS LED is Red, then the Termination Fault detection does not function and the TFxx LEDs are forced off. With the LOSEN register bit (bit 4 of register 05h) set, the ¯¯¯¯ LOS detection may still function while the cable driver is ¯¯¯¯ disabled. In this mode, LOS is combined with the ENABLE functionality, and if the input signal is removed then the cable driver will power down but keep the ¯¯¯¯ LOS detection running. The device will power back on once an input signal is detected. (While in this mode, disabling the device by pushing the ENABLE switch will still power down the device completely, including powering down Termination Fault and ¯¯¯¯ LOS detection).

Firmware Version – FW Ver FW Ver shows the version of the firmware installed on the evaluation board. Termination Fault These controls show the default configuration of the HD and SD Termination Fault Threshold registers and also provide the ability to change the thresholds. The LMH0307 has two pairs of Termination Fault Threshold registers – one HD/SD pair for each of its two output channels – as shown in Figure 4. The LMH0303 has only one HD/SD pair of Termination Fault Threshold registers for its single output channel, as can be seen in Figure 5. Increasing the Termination Fault Threshold settings decreases the cable driver’s sensitivity to Termination Faults. This is useful if the cable driver is indicating termination faults when the output appears to be properly terminated. Decreasing the Termination Fault Threshold settings increases the cable driver’s sensitivity to Termination Faults which is useful for determining cable detection at the end of long cables. Compare Command and Termination Fault Counters Compare Command configures the CMPCMD section of the TEST register (08h) on the LMH0303 or LMH0307. The Termination Fault Counters reflect the current configuration of the TEST register CMPCMD bits. The Termination Fault Counters provide an indication of how the cable driver is reading the Termination Faults based on the current Termination Fault Threshold settings. Perfectly terminated outputs should read back “0”, and unterminated outputs should read back “31”. Control Refresh The Refresh button provides a manual refresh of the state from the evaluation board to the LMH0303/LMH0307 tab. Changes to the board will not be reflected in the LED icons and Line Control checkboxes on the LMH0303/LMH0307 tab until the Refresh button is pressed. This can be done automatically by using the Auto Refresh checkbox. Auto Refresh Checkbox The Auto Refresh checkbox provides an automatic refresh of the state from the evaluation board to the LMH0303/LMH0307 tab once per second. This provides automatic updating of the LED icons and Line Control checkboxes on the LMH0303/LMH0307 tab to reflect any board changes. Line Control Power Down 0 and 1 (LMH0307 only) Power Down 0 and 1 checkboxes control the PD0 and PD1 power down bits (bits 5 and 6 in register 02h - MASK) and will selectively power down one or both of the output channels on the LMH0307. Enable The Enable checkbox controls the associated ENABLE pin on the LMH0303/LMH0307. Disabling or un-checking the Enable checkbox will force the LMH0303/LMH0307 into a deep power down mode. RSTI ¯¯¯¯ pin. This checkbox is checked for normal operation, and un-checked to put The RSTI checkbox controls the RSTI the cable driver in reset. SD303/SD307 EVK User Guide Rev 1.2 10 of 27 © 2010, National Semiconductor Corp. SD/HD The SD/HD checkbox controls the state of the SD/HD pin. This checkbox is un-checked by default to enable HD/3G mode. Enabling this checkbox sets the cable driver edge rates to SD mode. SDO Amp The SDO Amp controls set the amplitude of the output driver(s). The LMH0307 has two independently configurable outputs (SDO0 and SD01) and the LMH0303 has a single configurable output (SDO). For the LMH0307, SDO Amp 0 configures the AMP0 bits in the OUTPUT0 register (04h), and SDO Amp 1 configures the AMP1 bits in the OUTPUT1 register (06h). For the LMH0303, SDO Amp configures the AMP bits in the OUTPUT register (04h). The default amplitude setting is 0x10 for 800 mVP-P. The output amplitude may be lowered to around 720 mVP-P and increased to around 880 mVP-P in roughly 5 mV increments. LED Icons The diagram of the LMH0303/LMH0307 device is framed by a number of colored LED icons that represent the LED state on the board. Note that either the Refresh button or the Auto Refresh checkbox must be used to update the LED icons in the LMH0303/LMH0307 tab to reflect any board changes. FAULT LED The FAULT LED shows the current state of the ¯¯¯¯¯¯ FAULT pin. The FAULT LED is Green to indicate no faults are ¯¯¯¯¯¯ = 1) and Red to indicate one or more faults have been detected (FAULT ¯¯¯¯¯¯ = 0). The Auto Refresh detected (FAULT checkbox should be checked in order to actively monitor the state of the ¯¯¯¯¯¯ FAULT pin. ¯¯¯¯¯¯ FAULT is triggered and set low for a Termination Fault on any output or the loss of signal on the input. ¯¯¯¯¯¯ FAULT is cleared and set high again when the faults have been removed by either terminating the outputs, applying the input signal, or changing the register settings in the MASK or DIRECTION registers. Registers Tab The Registers tab displays all registers for the LMH0303 or LMH0307. Figure 6 shows the Registers tab for the LMH0307. The Value field indicates the value of the currently selected register. SD303/SD307 EVK User Guide Rev 1.2 11 of 27 © 2010, National Semiconductor Corp. Figure 6. LMH0307 Registers Tab Each register can be examined in detail by either double clicking on the desired registers fold bar (with the address and the register name, e.g. 0x00 – ID) or by single clicking the icon at the right of the fold bar (two inverted carats). The Refresh button will re-read the currently selected register and the Refresh All will read all registers in the device. Changes may be made to the registers by checking or un-checking the individual register bits or typing in a new register value in the Value field. After setting the appropriate register value, the Apply button must be pressed to apply the changes. The detailed view of the STATUS register is shown in Figure 7 with Verbose Descriptions checked and Figure 8 with Verbose Descriptions un-checked.

Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
