TECHNICAL DATA

IL145567

PCM CODEC - FILTER

IL145567N is a one-chip PCM-cofidec which converts speech signal

into digital form and backwards. The IC is design to operate in

synchronous and asynchronous systems and is comprised of:

- reference generator;

- filters on switching capacitors in transmission and receipt channels ;

- two operational amplifiers.

The IC does signal companding under the A-low and full differential

processing of analogue signals for reduction of noises. Typical

dissipated power is 40mW, under reduced power – 1 mW at ±5 V.
