Features
Functional Description
SMPTE-259M Operation
The CY7C9235A is a CMOS integrated circuit designed to
encode SMPTE-125M bit-parallel digital characters (or other
data formats) using the SMPTE-259M encoding rules.
Following encoding, the characters are output as bit-parallel
characters ready for serialization. The encoded outputs of the
CY7C9235A are designed to be directly mated to a CY7B9234
HOTLink transmitter, which then converts the bit-parallel
characters into a SMPTE-259M compatible high-speed serial
data stream.
• Fully compatible with SMPTE-259M
• Fully compatible with DVB-ASI
• Operates from a single +5V supply
• 44-pin PLCC package

This device performs both TRS (sync) detection and filtering,
data scrambling with the SMPTE-259M ×
and NRZ-to-NRZI encoding. 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 scrambler and NRZI encoding functions can be
disabled.
DVB-ASI Operation
The CY7C9235A also contains the necessary multiplexers,
control inputs, and outputs, to sequence out a DVB-ASI
compliant video stream. DVB-ASI operation is enabled
through activation of a single input signal. This allows a single
serial output port to support both SMPTE and DVB data
streams under software or hardware control.
In DVB-ASI mode the CY7C9235A operates with two enable
signals (ENA and ENN) to allow data to be presented from
either synchronous (clocked) or asynchronous FIFOs. When
data is not available, the CY7C9235A ensures that the proper
fill character (K28.5) is generated by the attached CY7B9234
serializer.
The CY7C9235A operates from a single +5V supply. It is
available in a 44-pin PLCC space saving package.
