A, Burlington, Ontario, Canada L7R 3Y3 Tel. +1 (905) 632-2996 Fax. +1 (905) 632-5946 E-mail: info@gennum.com www.gennum.com Revision Date: May 2005 Document No. 14583 - 04 DATA SHEET FEATURES • SMPTE 259M-C compliant (270Mb/s) • serializes 8-bit or 10-bit data • minimal external components (no loop filter components required) • isolated, dual-output, adjustable cable driver • 3.3V and 5.0V CMOS/TTL compatible inputs • lock detect indication • SMPTE scramble and NRZI coding bypass option • EDH support with GS9001, GS9021 • Pb-Free and RoHS Compliant APPLICATION SMPTE 259M-C parallel to serial interfaces for video cameras, VTRs, signal generators; Generic parallel to serial conversion. DESCRIPTION The GS7032 is designed to encode and serialize SMPTE 125M bit parallel digital video signals as well as other 8-bit or 10-bit parallel formats. This device performs the following functions: • sync detection • parallel to serial conversion • data scrambling (using the X 9 + X4 + 1 algorithm) • 10x parallel clock multiplication • conversion of NRZ to NRZI serial data The GS7032 features 270M/bs data rate with a single VCO resistor. Other features include a lock detect output, NRZI encoding and SMPTE scrambler bypass, a sync detect disable, and an isolated dual output cable driver suitable for driving 75 Ω loads.
