Overview
CY7C9335 SMPTE-259M/DVB-ASI Descrambler/Framer-Controller 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 • Decodes 10-bit parallel digital streams for any rate from 16−40 M characters/sec (160−400 Mbits/sec serial) • Operates with CY7B9334 SMPTE HOTLink™ deserializer/receiver • X9 + X4 + 1 descrambler and NRZI-to-NRZ decoder may be bypassed for raw data 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 X9 + X4 + 1 algorithm, and NRZI-to-NRZ decoding.
These functions operate at any character rate from 16 to 40 MHz.
For those systems operating 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, 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.
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.
Functional Description SMPTE-259M Operation The CY7C9335 is a CMOS integrated circuit designed to decode SMPTE-125M and SMPTE-244M bit-parallel digital characters (or other data fo...
