GS1575B / GS9075B HD-LINX® II Multi-Rate SDI Automatic Reclocker Features GS1575B • • • • • • • • • • • • • • • SMPTE 292M, 259M and 344M compliant Supports data rates of 143, 177, 270, 360, 540, 1483.5, 1485 Mb/s Supports DVB-ASI at 270Mb/s Pb-free and RoHS Compliant Auto and Manual Modes for rate selection Standards indication in Auto Mode 4:1 input multiplexer Loss of Signal (LOS) Output Lock Detect Output On-chip Input and Output Termination Differential 50Ω inputs and outputs Mute, Bypass and Autobypass functions SD/HD indication output to control GS1528A Dual Slew-Rate Cable Driver Single 3.3V power supply Operating temperature range: 0°C to 70°C Description The GS1575B/9075B is a Multi-Rate Serial Digital Reclocker designed to automatically recover the embedded clock from a digital video signal and re-time the incoming video data. The GS1575B Serial Digital Reclocker will recover the embedded clock signal and re-time the data from a SMPTE 292M, SMPTE 259M or SMPTE 344M compliant digital video signal. The GS9075B Serial Digital Reclocker will recover the embedded clock signal and re-time the data from a SMPTE 259M or SMPTE 344M compliant digital video signal. The GS1575B/9075B removes the high frequency jitter components from the bit-serial stream. Input termination is on-chip for seamless matching to 50Ω transmission lines. An LVPECL compliant output interfaces seamlessly to the GS1578A/GS9078A Cable Driver. The GS1575B/9075B can operate in either auto or manual rate selection mode. In Auto mode the device will automatically detect and lock onto incoming SMPTE SDI data signals at any supported rate. For single rate data systems, the GS1575B/9075B can be configured to operate in Manual mode. In both modes, the device requires only one external crystal to set the VCO frequency when not locked and provides adjustment free operation. In systems which require passing of non-SMPTE data rates, the GS1575B/9075B can be configured to either automatically or manually enter a bypass mode in order to pass the signal without reclocking. The ASI/177 input pin allows for manual selection of support of either 177Mb/s or DVB-ASI inputs. The GS1575B/9075B is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous sub-components are RoHS compliant.

When AUTO/MAN is LOW, SS[0:2] are inputs, forcing the PLL to lock only to a selected data rate .

This prevents a false lock to 177Mb/s when using DVB-ASI. When set LOW, 177Mb/s lock is possible, however, if a 270Mb/s ASI signal is applied, the device could false lock to the 177MHz signal. 28 LOCKED Output Lock Detect.

It will be set HIGH when the reclocker has locked to 143Mbps, 177Mbps, 270Mbps, 360Mbps, or 540Mbps. 33 SD (GS9075B only) Output This signal will go HIGH when the reclocker has locked to the input SD signal.

GS1575B / GS9075B HD-LINX® II Multi-Rate SDI Automatic Reclocker Data Sheet 40063 - 1 June 2009 18 of 28 4.6 4:1 Input Mux The 4:1 input mux allows the connection of four independent streams of video/data. There are four differential inputs (DDI[3:0] and DDI[3:0]). The active channel can be selected via the DDI_SEL[1:0] pins. Table 4-1 shows the input selected for a given state at DDI_SEL[1:0]. Table 4-1: Bit Pattern for Input Select DDI_SEL[1:0] 00 01 10 11 Selected Input DDI0 DDI1 DDI2 DDI3 The DDI inputs are designed to be DC interfaced with the output of the GS1524A/9064A Cable Equalizer. There are on chip 50Ω termination resistors which come to a common point at the DDI_VT pins. Connect a 10nF capacitor to this pin and connect the other end of the capacitor to ground. This terminates the transmission line at the inputs for optimum performance. If only one input pair is used, connect the unused positive inputs to +3.3V and leave the unused negative inputs floating. This helps to eliminate crosstalk from potential noise that would couple to the unused input pair. 4.7 Automatic and Manual Data Rate Selection The GS1575B/9075B can be configured to manually lock to a specific data rate or automatically search for and lock to the incoming data rate. The AUTO/MAN pin selects automatic data rate detection mode (Auto mode) when HIGH and manual data rate selection mode (Manual mode) when LOW. In Auto mode, the SS[2:0] bi-directional pins become outputs and the bit pattern indicates the data rate that the PLL is locked to (or previously locked to). The "search algorithm" cycles through the data rates and starts over if that data rate is not found (see Figure 4-3). POWER-UP 143 Mb/s 177 Mb/s 270Mb/s 360 Mb/s 1.485Mb/s (GS1575B only) 540 Mb/s Figure 4-3: Data Rate Search Pattern GS1575B / GS9075B HD-LINX® II Multi-Rate SDI Automatic Reclocker Data Sheet 40063 - 1 June 2009 19 of 28 In Manual mode, the SS[2:0] pins become inputs and the data rate can be programmed by the application layer. In this mode, the search algorithm is disabled and the PLL will only lock to the data rate selected. Table 4-2 shows the SS[2:0] pin settings for either the data rate selected (in Manual mode) or the data rate that the PLL has locked to (in Auto mode). Table 4-2: Data Rate Indication/Selection Bit Pattern SS[2:0] 000 001 010 011 100 101* Data Rate (Mb/s) 143 177 270 360 540 1485/1483.5 * This setting only applies to the GS1575B. For the GS9075B, when AUTO/MAN is LOW, the pin settings SS[0:2] = 101 will be ignored by the device. 4.8 Bypass Mode In Bypass mode, the GS1575B/9075B passes the data at the inputs directly to the outputs. There are two pins that control the bypass function: BYPASS and AUTOBYPASS. When BYPASS is set HIGH by the application layer, the GS1575B/9075B will be in Bypass mode. When AUTOBYPASS is set HIGH by the application layer, the GS1575B/9075B will be configured to enter Bypass mode only when the PLL has not locked to a data rate. When BYPASS is set HIGH, AUTOBYPASS will be ignored. When the PLL is not locked, and both BYPASS and AUTOBYPASS are set LOW, the serial digital output DDO/DDO will produce invalid data. GS1575B / GS9075B HD-LINX® II Multi-Rate SDI Automatic Reclocker Data Sheet 40063 - 1 June 2009 20 of 28 4.9 DVB-ASI Operation The GS1575B/9075B will also re-clock DVB-ASI at 270 Mb/s. When reclocking DVB-ASI data set the ASI/177 pin HIGH to prevent a false lock to 177Mb/s. If ASI/177 is not set HIGH, a false lock may occur since there is a harmonic present in idle patterns (K28.5) which is very close the 177 Mb/s data rate (EIC 1179). Note that setting the ASI/177 pin HIGH will disable the 177 Mb/s search when the device is in Auto mode, consequently the GS1575B/9075B will not lock to that data rate. 4.10 Lock and LOS Indicators The LOCKED signal is an active high output which indicates when the PLL is locked. The internal lock logic of the GS1575B/9075B includes a system which monitors the Frequency Acquisition Loop and the Phase Acquisition Loop as well as a monitor to detect harmonic lock. The LOS (Loss of Signal) output is an active HIGH output which indicates the absence of data transitions at the DDIx input. In order for this output to be asserted, transitions must not be present for a period of typically 5.14 us. After this output has been asserted, LOS will deassert typically 5.14 us after the appearance of a transition at the DDIx input. This timing relationship is shown in Figure 4-4: 5.14 us 5.14 us DATA LOS Figure 4-4: LOS signal timing NOTE: LOS is sensitive to transitions appearing at the input, and does not distinguish between transitions caused by input data, and transitions due to noise. GS1575B / GS9075B HD-LINX® II Multi-Rate SDI Automatic Reclocker Data Sheet 40063 - 1 June 2009 21 of 28 4.11 Output Drivers and Serial Clock Outputs The device’s serial digital data outputs (DDO/DDO) have a nominal voltage of 800mv single ended or 1600mV differential when terminated into a 50Ω load. The GS1575B/9075B may also be configured to output a serial clock at the data output rate. The internal serial clock output block is powered via the SCO_ENABLE pin. When SCO_ENABLE is connected to VCC, a differential serial clock output will be present on SCO/SCO. Otherwise, when SCO_ENABLE is connected to GND, the clock output block will be powered down and the device will have reduced power consumption. NOTE: The SCO_ENABLE signal should have a 1.5mA drive strength to maintain a supply voltage of 3.3 +/- 0.165V. Clock and data alignment is shown in Figure 4-5. DATA SCLK For HD-SDI: t CD = 32ps (typ.), 36ps (max.) For SD-SDI: t CD = 30ps (typ.), 38ps (max.) tCD Figure 4-5: Clock and Data Alignment 4.12 Output Mute The DDO_MUTE pin is provided to allow muting of the re-timed output. When the PLL is locked and the device is reclocking, setting DDO_MUTE = LOW will force the serial digital outputs DDO/DDO to mute. However, if the GS1575B/9075B is in Bypass mode, (AUTOBYPASS = HIGH and/or BYPASS = HIGH), DDO_MUTE will have no effect on the output.
