ETC5067D-X Datasheet PDF - ST Microelectronics

●DESCRIPTION

●The ETC5064 (µ-law), ETC5067 (A-law) are mono lithic PCM CODEC/FILTERS utilizing the A/D and

●D/A conversion architecture shown in the Block Diagrams and a serial PCM interface. The devices are

●fabricated using double-poly CMOS process.
