September 2012 SD3GDAIII User’s Guide 1 Introduction The SD3GDAIII is a kit containing an evaluation board which is functionally an SDI Distribution Amplifier with a serial interface to allow connection to a host computer and a graphical user interface (GUI) program which allows the configuration of the devices on the board to be changed as desired, and allows for some measurements to be made on the board. SD3GDA III User’s Guide Lit#SNLU112 September 2012 2 Setup 2.1 Software Installation A copy of the install program can be obtained either from the CD encosed with the kit or downloaded from http://www.ti.com/tool/sd3gdaiii. This installer will run and give you this initial window: Once the installer has initialized, it will prompt you for locations to store the files. The SD3GDAIII GUI is built on the National Instruments LabView platform, so in addition to the GUI files, the installer will install some National Instruments software. September 2012 SD3GDAIII User’s Guide 2 2.2 Connecting the Evaluation Board The SD3GDAIII requires an external power source – it will do it’s own power regulation, so any power supply from 12V to 20VDC may be used, connect power via the spade terminals at the top of the board. Once power is applied, connect the board to a USB port on the host computer with the enclosed cable, and provide the input with an SDI source signal. The source can be any of the 270Mbps, 1.5Gbps or 3Gbps data rates. Presence of an input signal is indicated with the ‘CD’ (carrier detect) LED close to J3 – the SDI input port. There are four BNC output connectors. Each output has the option for on board termination in the event that the output is not being used. The bottom connector, J9 has R32 as it’s termination resistor, and as shipped, R32 is NOT installed – this means that J9, SDO- may be used as the primary output. The other three outputs (SDO+, SDO1- and SDO1-) have the termination resistor installed, so that the cable driver will see properly terminated outputs. If you want to use these outputs, remove the corresponding termination resistors (R23, R18 and R25). 3 SD3GDA III User’s Guide Lit#SNLU112 September 2012 2.3 Jumper and Option Settings The SD3GDAIII has 5 locations for Jumper blocks, and several other option settings that are enabled/disabled with 0Ω resistors. Jumper Function when installed P1 Disables SDO1 (Output to Media Card) on LMH0395 P2 Disables SDO0 (Output to LMH0376) on LMH0395 JP1 Forces Cable driver into HD/3G mode JP2 If in Pin Mode (via R15) then this makes the SDO1 on the LMH0376 the recovered clock JP5 If LMH0376 is in pin mode, a jumper here places the reclocker in Bypass September 2012 SD3GDAIII User’s Guide 4 3 Running the GUI 3.1 Overview Once setup, start the SD3GDAIII GUI, and it should open with a block diagram of the board: From this page, you can select what to do next via the selection panel on the left of the screen. 3.2 Direct Read/Write to registers The first option, ‘Low Level Configuration’ will allow you to examine individual register contents and write to them. Clicking on this option will bring up this screen: 5 SD3GDA III User’s Guide Lit#SNLU112 September 2012 This screen shows each of the registers for each of the chips in the signal path on the board, and for each register it will show what the last value read from that register was, what the last value written was, and by clicking on one of the registers, it will give detail on each of the bits in the register. You can read individual registers and you can write to the individual registers through this page. If you set up a particular configuration for a part which you would like to reuse in the future, you can use the ‘Save Configuration’ and ‘Load Configuration’ buttons to save and recover settings for a part. 3.3 Equalizer Control Page Selecting the Equalizer page brings up a page which reports the status of the equalizer, Some of the settings, such as the output settings can be set, but many of the other fields report status of the device. September 2012 SD3GDAIII User’s Guide 6 3.4 Reclocker Control Page The reclocker page allows you to control the LMH0376 – there are output setting to allow the two outputs to be independently controlled for amplitude, offset and de-emphasis. If the LMH0376 is locked, this will be shown with the green indicator on the bottom left of the page, and the nominal rate at which the device is locked is shown. The user will also be able to read the Horizontal eye opening, and Vertical eye opening values from the GUI. 7 SD3GDA III User’s Guide Lit#SNLU112 September 2012 3.5 Eye Monitor Page 4 Media Card The SD3GDAIII card has a media card inserted in the signal path between the equalizer and the reclocker. This card may be inserted in order to insert 25cm, 50cm or 100cm of PCB trace between the equalizer and the reclocker, to help the user to better simulate the use of the parts in a real system. Insert the media card into the MEDIA BOARD CONNECTOR – the length of trace is shown on the media card next to the fingers. There is also an option to use another card, connected with the SMA connectors on the Media Card, if the card is inserted appropriately.

These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use these EVMs. Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected. Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause September 2012 28 SD3GDAIII User’s Guide severe personal injury or death, such as devices which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate Assurance and Indemnity Agreement.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
