1 / 7 page GENLINXTM GS9022A Digital Video Serializer FUNCTIONAL BLOCK DIAGRAM FEATURES DEVICE DESCRIPTION The GS9022A is a drop-in replacement for the GS9022 in existing applications The GS9022A is a monolithic bipolar integrated circuit designed to serialize SMPTE 125M and SMPTE 244M bit parallel digital signals as well as other 8 or 10 bit parallel formats. This device performs the functions of sync detection, parallel to serial conversion, data scrambling (using the X9 + X4 +1 algorithm), 10x parallel clock multiplication and conversion of NRZ to NRZI serial data. The data rate is automatically set for SMPTE 259M data rates to 400 Mb/s. Other features include a lock detect output and an internal cable driver capable of driving two 75 Ω loads. The device requires a single +5 volt or -5 volt supply and typically consumes 650 mW of power while driving two 75 Ω loads. The 28 pin PLCC packaging assures a small footprint for the complete encoder function. • built-in 75 W cable driver with two serial outputs • standard independent operation • space saving 28 pin PLCC package • 650 mW typical power dissipation (data output driving 75 W load). • supports bit rates to 400 Mb/s • accepts 8 bit and 10 bit TTL and CMOS compatible parallel data inputs • fully compatible with SMPTE 259M serial digital standard • single +5 or -5 volt supply • Pb-free and Green APPLICATIONS •4ƒ SC, 4:2:2 and 360 Mb/s serial digital interfaces for: Video cameras VTRs Signal generators Portable equipment DATA SHEET ORDERING INFORMATION Revision Date: June 2004 Document No. 18325 - 01 GENNUM CORPORATION P.O.
