SMPTE 259M Digital Video Serializer with EDH
Generation/Insertion
General Description
The CLC021 SMPTE 259M Digital Video Serializer with EDH
Generation and Insertion is a monolithic integrated circuit
that encodes, serializes and transmits bit-parallel digital data
conforming to SMPTE 125M and 267M component video
and SMPTE 244M composite video standards. The CLC021
can also serialize other 8- or 10-bit parallel data. The
CLC021 operates at data rates from below 100 Mbps to over
400 Mbps. The serial data clock frequency is internally gen-
erated and requires no external frequency setting, trimming
or filtering components*.
Functions performed by the CLC021 include: parallel-to-
serial data conversion, ITU-R BT.601-4 input data clipping,
data encoding using the SMPTE polynomial (X
9
+X
4
+1), data
format conversion from NRZ to NRZI, parallel data clock fre-
quency multiplication and encoding with the serial data, and
differential, serial output data driving. The CLC021 has cir-
cuitry for automatic EDH character and flag generation and
insertion per SMPTE RP-165. The CLC021 has an exclusive
built-in self-test (BIST) and video test pattern generator
(TPG) with 16 component video test patterns: reference
black, PLL and EQ pathologicals and modified colour bars in
4:3 and 16:9 raster formats for NTSC and PAL formats*.
The CLC021 has inputs for enabling sync detection, non-
SMPTE mode operation, enabling the EDH function, NRZ/
NRZI mode control and an external reset control. Outputs
are provided for H, V and F bits, new TRS sync character po-
sition indication, ancilliary data header detection, NTSC/PAL
raster indication and PLL lock detect. Separate power pins
for the output driver, VCO and the serializer improve power
supply rejection, output jitter and noise performance.
The CLC021VGZ-5.0V is powered by a single +5V supply.
The CLC021VGZ-3.3V is powered by a single +3.3V supply.
Power dissipation is typically 235 mW including two 75
back-matched output loads. The device is packaged in a
JEDEC metric 44-lead PQFP.
