eatures - SMPTE 292M and SMPTE 259M-C pliant descrambling and NRZI → NRZ decoding (with bypass) DVB-ASI sync word detection and 8b/10b decoding auto-configuration for HD-SDI, SD-SDI and DVB-ASI serial loop-through cable driver output selectable as reclocked or non-reclocked (GS1560A only) dual serial digital input buffers with 2 x 1 mux integrated serial digital signal termination integrated reclocker automatic or manual rate selection / indication (HD/SD) descrambler bypass option user selectable additional processing Features including: - - - - - - - - - - - - - CRC, TRS, ANC data checksum, line number and EDH CRC error detection and correction programmable ANC data detection illegal code remapping Description The GS1560A/GS1561 is a reclocking deserializer. When used in conjunction with the GS1524 Automatic Cable Equalizer and the GO1525 Voltage Controlled Oscillator, a receive solution can be realized for HD-SD, SD-SDI and DVB-ASI applications. In addition to reclocking and deserializing the input data stream, the GS1560A/GS1561 performs NRZI-to-NRZ decoding, descrambling as per SMPTE 259M-C/292M, and word alignment when operating in SMPTE mode. When operating in DVB-ASI mode, the device will word align the data to K28.5 sync characters and 8b/10b decode the received stream. Two serial digital input buffers are provided with a 2x1 multiplexer to allow the device to select from one of two serial digital input signals. The integrated reclocker Features a very wide Input Jitter Tolerance of ±0.3 UI (total 0.6 UI), a rapid asynchronous lock time, and full pliance with DVB-ASI data streams. The GS1560A includes an integrated cable driver is for serial input loop-through applications. It can be selected to output either buffered or reclocked data. The cable driver also Features an output mute on loss of signal, high impedance mode, adjustable signal swing, and automatic dual slew-rate selection depending on HD/SD operational requirements. The GS1560A/GS1561 also...
