When used in conjunction with a GS9064 automatic cable equalizer and a GO1525 voltage controlled oscillator, a 270Mb/s receive solution can be realized for SD-SDI and DVB-ASI. In addition to providing robust serial to parallel conversion with word alignment, the GS9060 includes a range of additional data processing functions such as error detection and correction, automatic standards detection, DVB-ASI and EDH support. After reclocking and serial-to-parallel conversion, the device performs NRZI to NRZ decoding, de-scrambling as per SMPTE 259M and word alignment of the incoming data stream. The SMPTE de-scrambler and word alignment features can optionally be bypassed to support the reception of signals with other coding schemes. Two serial digital input buffers are provided with a 2x1 multiplexer. This allows the device to select from one of two serial digital input signals. The integrated reclocker features a very wide Input Jitter Tolerance (IJT) of ±0.3 UI, a rapid (typically less than 265µs) asynchronous lock time, and full compliance with DVB-ASI data streams. A SMPTE 259M-C compliant cable driver output is also provided for serial input loop through applications. The serial digital output can be selected as either before or after the integrated reclocker. The cable driver also features an output mute on loss of signal, high impedance mode and adjustable signal swing. The GS9060 also features a number of signal integrity checks and measurement capabilities. TRS errors, EDH CRC errors and ancillary data check sum errors can all be detected. A single 'error' pin is provided which is a logical 'or'ing of all the detected errors. Individual error status can be read from the host interface port. In addition to detecting signal errors, the device also includes the ability to correct all of the above detected errors. Each error correction function may be individually enabled / disabled via host interface control.

Other processing functions include H:V:F timing extraction, Y and C ancillary data indication and video standard indication. The device may also be used in data pass through mode where no processing of the data is performed. Parallel data outputs are provided in both 10 bit multiplexed and 20 bit de-multiplexed format. An associated parallel clock output signal is provided operating at 27 MHz (10 bit multiplexed and DVB-ASI output) and 13.5 MHz (20 bit demultiplexed output).
MASTER_SLAVE SMPTE_BYPASS
When configured for DVB-ASI operation, the DVB-ASI data will be word aligned to K28.5 sync characters and 8b/10b decoding is applied to the received data stream. Line number generation is also performed by the device. As well as detecting and extracting SMPTE 352M payload identifier packets, the GS9060 can also automatically identify the received video standard and the payload data type. The detected video standard and data format may be read via the host interface port.
