When used in conjunction with any Gennum cable equalizer and the GO1555/GO1525* Voltage Controlled Oscillator, a received solution can be realized for SD-SDI and DVB-ASI applications. In addition to reclocking an deserializing the input data stream, the GS9060 performs NRZI-to-NRZ decoding, descrambling as per SMPTE 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 compliance 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 signal swing. The GS9060 also includes a range of data processing functions such as error detection and correction, automatic standards detection, and EDH support. The device can also detect and extract SMTPTE 352M payload identifier packets and independently identify the received video standard. This information is read from internal registers via the host interface port. TRS errors, EDH CRC errors and ancillary data checksum errors can all be detected. A single ‘DATA_ERROR’ pin is provided which is a logical ‘ORing’ of all detectable errors. Individual error status is stored in internal ‘ERROR_STATUS’ registers. Finally the device can correct detected errors and insert new TRS ID words, ancillary data checksum words, and EDH CRC words. Illegal code re-mapping is also available. All processing functions may be individually enabled or disabled via the host interface control. The GS9060 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant (RoHS compliant). *For new designs use GO1555 |
