Description

The GS1522 is a monolithic bipolar integrated circuit designed to serialize SMPTE 274M and SMPTE 260M bit parallel digital signals.

GS1522 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 X⁹ +X⁴ +1 algorithm)
• Conversion of NRZ to NRZI serial data (using the (X+1) algorithm)
• Selectable DUAL or QUAD 75Ω Cable Driver outputs
• Lock Detect Output
• 1.485Gb/s or 1.485/1.001Gb/s operation

GS1522 requires a single 5V supply and typically consumes less than 1000mW of power while driving two 75Ω cables.

The GS1522 uses the GO1515 external VCO connected to the internal PLL circuitry to achieve ultra low noise PLL performance.
