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 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 APPLICATIONS •4ƒ SC, 4:2:2 and 360 Mb/s serial digital interfaces for: Video cameras VTRs Signal generators Portable equipment DATA SHEET Part Number Package Temperature GS9022-CPJ 28 pin PLCC O °C to 70°C GS9022-CTJ 28 pin PLCC Tape O °C to 70°C ORDERING INFORMATION Revision Date: August 1997 Document No. 521 - 42 - 01 |
