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? 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

? 4?SC, 4:2:2 and 360 Mb/s serial digital interfaces for:

Video cameras VTRs

Signal generators Portable equipment
