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:

鈥?/div>

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 +X +1 algorithm)

Conversion of NRZ to NRZI serial data (using the (X+1)

algorithm)

Selectable DUAL or QUAD 75鈩?Cable Driver outputs

Lock Detect Output

1.485Gb/s or 1.485/1.001Gb/s operation

鈥?/div>

This device requires a single 5V supply and typically

consumes less than 1000mW of power while driving two

75鈩?cables.

The GS1522 uses the GO1515 external VCO connected to

the internal PLL circuitry to achieve ultra low noise PLL

performance.
