DESCRIPTION
The CLC020 SMPTE 259M Digital Video Serializer
with Integrated Cable Driver is a monolithic integrated
circuit that encodes, serializes and transmits bit-
parallel digital data conforming to SMPTE 125M and
SMPTE 267M component video and SMPTE 244M
composite video standards. The CLC020 can also
serialize other 8 or 10-bit parallel data. The CLC020
operates at data rates from below 100 Mbps to over
400 Mbps. The serial data clock frequency is
internally generated and requires no external
frequency setting components, trimming or filtering*.
Functions performed by the CLC020 include: parallel-
to-serial data conversion, data encoding using the
polynomial (X⁹+X⁴+1), data format conversion from
NRZ to NRZI, parallel data clock frequency
multiplication and encoding with the serial data, and
coaxial cable driving. Input for sync (TRS) detection
disabling and a PLL lock detect output are provided.
The CLC020 has an exclusive built-in self-test (BIST)
and video test pattern generator (TPG) with 4
component video test patterns, reference black, PLL
and EQ pathologicals and modified colour bars, in 4:3
and 16:9 raster and both NTSC and PAL formats*.
Separate power pins for the output driver, VCO and
the digital logic improve power supply rejection,
output jitter and noise performance.
The CLC020 is the ideal complement to the
CLC011B SMPTE 259M Serial Digital Video
Decoder, CLC014 Active Cable Equalizer, CLC016
Data Retiming PLL (clock-data separator), CLC018
8X8 Digital Crosspoint Switch and CLC006 or
CLC007 Cable Drivers, for a complete parallel-serial-
parallel, high-speed data processing and
transmission system.
The CLC020 is powered from a single 5V supply.
Power dissipation is typically 235 mW including two
75Ω back-matched output loads. The device is
packaged in a JEDEC 28-lead PLCC.
