Product Overview

The TP3054N/NOPB is a 16-pin Enhanced Serial Interface Codec/Filter Combo for D3/D4 and CCITT applications. The TP3054 family consists of µ-law monolithic PCM codec/filter utilizing the A/D and D/A conversion architecture and a serial PCM interface. 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 200Hz and above 3400Hz. Also included are auto-zero circuitry and a companding coder which samples the filtered signal and encodes it in the companded µ-law PCM format. The decode portion of each device consists of an expanding decoder, which reconstructs the analogue signal from the companded µ-law or A-law code, a low-pass filter which corrects for the sin x/x response of the decoder output and rejects signals above 3400Hz followed by a single-ended power amplifier capable of driving low impedance loads.
