CY7C9335  
SMPTE-259M/DVB-ASI  
Descrambler/Framer-Controller  
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.  
Features  
Fully compatible with SMPTE-259M  
— SMPTE-125M compliant for 4:2:2 component video  
— SMPTE-244M compliant for 4fsc composite video  
Fully compatible with DVB-ASI  
Operates from a single +5V or 5V supply  
100-pin TQFP package  
This device performs both TRS (sync) detection and framing,

data descrambling with the SMPTE-259M X + X + 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.  
Decodes 10-bitparallel digital streams for any rate from  
16 40 M characters/sec (160 400 Mbits/sec serial)  
Operates with CY7B9334 SMPTE HOTLink™ deserializ-  
er/receiver  
X + X + 1 descrambler and NRZI-to-NRZ decoder may  
be bypassed for raw data output  
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.  
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.  
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.
