DATA SHEET

FEATURES

DEVICE DESCRIPTION

• built-in 75 Ωcable driver with two serial outputs

• standard independent operation

• space saving 28 pin PLCC package

TheGS9022isamonolithicbipolarintegratedcircuitdesigned

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

NRZIserialdata. Thedatarateisautomaticallyset forSMPTE

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.

• 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

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.

• fully compatible with SMPTE 259M serial digital

standard

• single +5 or -5 volt supply
