3.1 Functional Overview
The GS9090A is a 270Mb/s reclocking deserializer with an internal FIFO and
programmable multi-function output port. The device has two basic modes of
operation which determine precisely how SMPTE or DVB-ASI compliant input data
streams are reclocked and processed.
In Auto mode (AUTO/MAN = HIGH), the GS9090A will automatically detect,
reclock, deserialize, and process SD SMPTE 259M-C, or DVB-ASI input data.
In Manual mode (AUTO/MAN = LOW), the application layer must set external
device pins for the correct reception of either SMPTE or DVB-ASI data. Manual
mode also supports the reclocking and deserializing of 270Mb/s data not
conforming to SMPTE or DVB-ASI streams.
The digital signal processing core implements several data processing functions
including error detection and correction and automatic video standards detection.
These features are all enabled by default, but may be individually disabled via
internal registers accessible through the GSPI host interface.
The provided programmable multi-function output pins may be configured to output
various status signals including H, V, and F timing, ancillary data detection, EDH
detection, and a FIFO load pulse. The internal FIFO supports 4 modes of
operation, which may be used for data alignment / delay, MPEG packet extraction,
or ancillary data extraction.
The GS9090A contains a JTAG interface for boundary scan test implementations.
