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 whic.
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. The decode portion of each device consists of an expanding decoder, which reconstructs the analog signal from the companded A-law or µ
–law code, a low-pass filter which corrects for the sin x/.
