CY7C9335

SMPTE-259M/DVB-ASI

Descrambler/Framer-Controller

1CY7C9335

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

• Decodes10-bitparalleldigitalstreamsforanyratefrom

16-40 M characters/sec (160-400 Mbits/sec serial)

• Operates with CY7B9334 SMPTE HOTLink™ deserializ-

This device performs both TRS (sync) detection and framing,

data descrambling with the SMPTE-259M X⁹+ X⁴+ 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.

• X⁹+ X⁴+ 1 descrambler and NRZI-to-NRZ decoder may

be bypassed for raw data output

Functional Description

SMPTE-259M Operation

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 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 CY7C9335 operates from a single +5V or −5V supply. It is

available in a 100-pin TQFP space saving package.
