... MAXIMIZES LINE INTERFACE CARD CIR- CUIT DENSITY OPERATION DESCRIPTION The ETC5057/ETC5054 family consists of A-law and –law monolithic PCM CODEC/filters utilizing the A/D and D/A conversion architecture shown in the block diagram below, and a serial PCM inter- face. The devices are fabricated using double- poly CMOS process ...
