.. GS1559 HD-LINX™ II Multi-Rate Deserializer with Loop-Through Cable Driver GS1559 Data Sheet Key Features - 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 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 GS1559 is a reclocking deserializer with a serial loop-through cable driver. When used in conjunction with the GS1574 Automatic Cable Equalizer and the GO1525 Voltage Controlled Oscillator, a receive solution can be realized for HD-SDI, SD-SDI and DVB-ASI applications. In addition to reclocking and deserializing the input data stream, the GS1559 performs NRZI-to-NRZ decoding, descrambling as per SMPTE 292M/259M-C, 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. An integrated cable driver is provided for serial input loop-through applications and can be selected to output either buffered or reclocked data. This cable driver also Features an output mute on loss of signal, high impedance mode, adjustable...
