SMPTE 259M Digital Video Serializer with Integrated
Cable Driver
General DescriptionThe CLC020 SMPTE 259M Digital Video Serializer with Inte-
grated Cable Driverisa monolithic integrated circuit that en-
codes, serializes and transmits bit-parallel digital data con-
formingto SMPTE 125M and SMPTE 267M component
video and SMPTE 244M composite video standards. The
CLC020 can also serialize other8or 10-bit parallel data. The
CLC020 operatesat data rates from below 100 Mbpsto over
400 Mbps. The serial data clock frequencyis internally gen-
erated and requiresno external frequency setting compo-
nents, trimmingor filtering*. Functions performedby the
CLC020 include: parallel-to-serial data conversion, data en-
coding usingthe polynomial(X9+X4+1), data format conver-
sion from NRZto NRZI, parallel data clock frequency multi-
plication and encoding withthe serial data, and coaxial cable
driving. Inputfor sync (TRS) detection disabling anda PLL
lock detect output are provided. The CLC020 hasan exclu-
sive built-in self-test (BIST) and video test pattern generator
(TPG) with4 component video test patterns, reference
black, PLLandEQ pathologicals and modified colour bars,in
4:3 and 16:9 raster and both NTSC and PAL formats*. Sepa-
rate power pinsfor the output driver, VCO and the digital
logic improve power supply rejection, output jitter and noise
performance.
The CLC020is the ideal complementto 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, fora complete
parallel-serial-parallel, high-speed data processing and
transmission system.
The CLC020is powered froma single5V supply. Power dis-
sipation is typically 235 mW including two 75Ω
back-matched output loads. The deviceis packagedina
JEDEC 28-lead PLCC.
Features SMPTE 259M serial digital video standard compliant No external serial data rate settingor VCO filtering
