Functional Description
SMPTE-259M Operation
The CY7C9335 is a CMOS integrated circuit designed to de-
code SMPTE-125M and SMPTE-244M bit-parallel digital char-
acters (or other data formats) using the SMPTE-259M decod-
ing rules. Following decoding, the characters are framed by
locating the 30-bit TRS pattern in the parallel character
stream. The framed characters are then output.
The inputs of the CY7C9335 are designed to be directly mated
to a CY7B9334 HOTLink receiver, which converts the
SMPTE-259M compatible high-speed serial data stream into
10-bit parallel characters.
This device performs both TRS (sync) detection and framing,
data descrambling with the SMPTE-259M X
9
+ X
4
+ 1 algo-
rithm, and NRZI-to-NRZ decoding. These functions operate at
any character rate from 16 to 40 MHz. For those systems op-
erating with non-SMPTE-259M compliant video streams (or for
diagnostic purposes), the descrambler and NRZI decoding
functions can be disabled.
DVB-ASI Operation
The CY7C9335 also contains the necessary multiplexers, con-
trol inputs and outputs, to control a DVB-ASI compliant video
stream. DVB-ASI operation is enabled through activation of a
single input signal. This allows a single serial-to-parallel input
port to support both SMPTE and DVB data streams under soft-
ware or hardware control.
In DVB-ASI mode the CY7C9335 automatically enables both
the 8B/10B decoder and multi-byte framer present in the
CY7B9334 receiver/deserializer. All error detection, fill, and
command codes are detected and output by the CY7C9335.
The CY7C9335 operates from a single +5V or
5V supply. It is
available in a 100-pin TQFP space saving package.
