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: August 1999 Document No. 522 - 06 - 02 PRELIMINARY DATA SHEET FEATURES • fully integrated 270Mb/s SDI receiver or transmitter • fully compliant with SMPTE 259M-C • lock and carrier detect output indication • performance from 0 - 85°C RECEIVER FUNCTION • accepts SMPTE 259M-C 270Mb/s serial digital video and outputs SMPTE 125M compliant 27Mb/s parallel digital video and clock • integrated cable equalization (beyond 100m Belden 8281) • ease of design use and adjustment free operation • H timing signal output TRANSMITTER FUNCTION • accepts SMPTE 125M (27Mb/s) parallel video data and clock, outputs SMPTE 259M-C 270Mb/s serial digital video • integrated cable driver provides one differential output (or two single-ended outputs) APPLICATIONS Space limited, low power 270Mb/s serial to parallel or parallel to serial interfaces; Alternate, broadcast quality uncompressed video interface for industrial and professional video equipment using the IEEE P1394 interface. DESCRIPTION The GS7000 is a dual function IC capable of operating as either a 270Mb/s Serial Digital Video receiver or a 270Mb/s Serial Digital Video transmitter. The GS7000 is designed so that it can be programmed to operate in either receive or transmit mode via a mode select pin. When operating as a receiver, the serial data input accepts SMPTE 259M-C compliant signals. Line terminations are on the device. An on-chip by-passable fixed gain equalizer provides cable equalization beyond 100m of high quality co-axial cable. The clock recovery is performed on chip with minimal external components. Incoming Serial Digital Video data is decoded using a NRZI decoder and SMPTE descrambler to provide clocked SMPTE 125M compliant parallel output. The SMPTE descrambler and NRZI decoding functions can be disabled. When operating as a transmitter, the GS7000 accepts parallel SMPTE 125M compliant ten bit video. An on-chip scrambler and NRZI encoder converts the parallel data into a bit serial SMPTE 259M-C compliant NRZI output signal suitable for driving co-axial cable. Through the SMPTE select pin, the SMPTE scrambler and NRZI coding functions can be disabled.
