DESCRIPTION
The GS1522 is a monolithic bipolar integrated circuit
designed to serialize SMPTE 274M and SMPTE 260M bit
parallel digital signals.
This device performs the following functions:
Sync word mapping for 8-bit/10-bit operation.
Parallel to Serial conversion of Luma & Chroma data
Interleaving of Luma and Chroma data
Data Scrambling (using the X

+1 algorithm)
Conversion of NRZ to NRZI serial data (using the (X+1)
algorithm)
Selectable DUAL or QUAD 75
Cable Driver outputs
Lock Detect Output
1.485Gb/s or 1.485/1.001Gb/s operation
This device requires a single 5V supply and typically
consumes less than 1000mW of power while driving two
75
cables.
The GS1522 uses the GO1515 external VCO connected to
the internal PLL circuitry to achieve ultra low noise PLL
performance.
