PT2395
DESCRIPTION
PT2395 is a silicon gate CMOS-processed digital echo IC functionally compatible with M50195P. Input signal to PT2395 is converted to digital signal with A-D conversion then stored in the memory (DRAM) chip. After a certain delay time, digital signal is read out from the memory chip and then converted back into analog signal using the D-A conversion. A low cost echo system may thus be achieved with PT2395’s A-D converter, D-A converter, incorporating ADM algorithm, while maintaining lower noise, lower distortion, higher S/N ratio as compared to the conventional BBD (Bucket Brigate Device).
