ETC5054D - Brand New STMicroelectronics Interface - CODECs
-
DESCRIPTION
The ETC5057/ETC5054 family consists of A-law and µ–law monolithic PCM CODEC/filters utilizing the A/D and D/A conversion architecture shown in the block diagram below, and a serial PCM interface. The devices are fabricated using doublepoly CMOS process. The encode portion of each device consists of an input gain adjust amplifier, an active RC pre-filter which eliminates very high frequency noise prior to entering a switched-capacitor band-pass filter that rejects signals below 200 Hz and above 3400 Hz. Also included are auto- zero circuitry and a companding coder which samples the filtered signal and encodes it in the companded A-law or µ–law PCM format.
