Reclocking Deserializer with a Serial Loop-through Cable Driver

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, and automatic dual slew-rate selection depending on HD/SD operational requirements.

The GS1559 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 SMPTE 352M payload identifier packets and independently identify the received video standard. This information is read from internal registers via the host interface port.

Line-based CRC errors, line number errors, 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 'OR'ing 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, line-based CRC words, ancillary data checksum words, EDH CRC words, and line numbers. Illegal code re-mapping is also available. All processing functions may be individually enabled or disabled via host interface control. * For new designs use GO1555.
