DESCRIPTION

The STV1602Ais a Hybrid IC decoder which converts serial data coming from a serial transmission line into parallel data.

BUILT-IN AUTOMATIC EQUALIZER FOR UP TO 30dB ATTENUATION AT 135MHz (TYPICALLY 300m OF HIGH-GRADE COAXIAL CABLE), PLL CIRCUIT FOR RECLOCKING, ANDSERIAL-PARALLEL CONVERSION CIRCUIT.

THIS SERIAL TRANSMISSION DECODER REQUIRESONLY FEW EXTERNAL COMPONENTS. OTHER RELATED IC’s INCLUDE :

■ STV1601A, A SERIAL TRANSMISSION ENCODER (PARALLEL-TO-SERIAL CONVERSION)

■ STV1389AQ COAXIAL CABLE DRIVER

FUNCTIONS

■ Cable equalizer (maximum gain : 30dB at 135MHz)

■ PLL for serial clock generation

■ Reclocked repeater output (active loop through)

■ Descrambler : modulo-2 multiplication by G(x) = (x9 + x4 + 1) (x + 1)

■ Parallel-to-serial conversion

■ Sync monitor output

■ Eye pattern monitoring

■ Input signal detector
