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 9+X4+1 algorithm) • Conversion of NRZ to NRZI serial data (using the (X+1) algorithm) • Selectable DUAL or QUAD 75 Ω 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 Ω cables. The GS1522 uses the GO1515 external VCO connected to the internal PLL circuitry to achieve ultra low noise PLL performance.
