CY7C9335A  
SMPTE-259M/DVB-ASI  
Descrambler/Framer-Controller  
The inputs of the CY7C9335A 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  
• Fully compatible with DVB-ASI  
• Operates from a single +5V supply  
• 100-pin TQFP package  
This device performs both TRS (sync) detection and framing,  
data descrambling with the SMPTE-259M X9+X4+1 algorithm,  
and NRZI-to-NRZ decoding. These functions operate at a 27  
MHz character rate. For those systems operating with  
non-SMPTE-259M compliant video streams (or for diagnostic  
purposes), the descrambler and NRZI decoding functions can  
be disabled.  
• Decodes 10-bit parallel digital streams for 27M  
characters/sec (270 Mbits/sec serial)  
• Operates with CY7B9334 SMPTE HOTLink deseri-  
alizer/receiver  
• X9 + X4 + 1 descrambler and NRZI-to-NRZ decoder may  
be bypassed for raw data output  
DVB-ASI Operation  
The CY7C9335A also contains the necessary multiplexers,  
control 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 software or hardware control.  
Functional Description  
SMPTE-259M Operation  
The CY7C9335A is a CMOS integrated circuit designed to  
decode SMPTE-125M bit-parallel digital characters (or other  
data formats) using the SMPTE-259M decoding 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 CY7C9335A automatically enables both  
the 8B/10B decoder and multibyte framer present in the  
CY7B9334 receiver/deserializer. All error detection, fill, and  
command codes are detected and output by the CY7C9335A.  
The CY7C9335A operates from a single +5V supply. It is  
available in a 100-pin TQFP space saving package.
