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 75Ω loads.

FEATURES

• built-in 75 Ω cable driver with two serial outputs

• standard independent operation

• space saving 28 pin PLCC package

• 650 mW typical power dissipation (data output driving 75 Ω 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

• 4ƒSC, 4:2:2 and 360 Mb/s serial digital interfaces for:

Video cameras VTRs

Signal generators Portable equipment
