Gennum GS9022A

Digital Video Serializer PLCC-28

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.

Features

• Built-in 75Ω cable driver with two serial outputs
• Standard independent operation
• 650 mW typical power dissipation
• Supports bit rates up to400 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
• 28-PLCC package

Applications

• 4fSC, 4:2:2 and 360 Mb/s serial digital interfaces for video cameras, VTRs, signal generators and portable equipment
