TP3054, TP3057
‘‘Enhanced’’ Serial Interface CODEC/Filter COMBOÉ Family
General Description
The TP3054, TP3057 family consists of m-law and A-law monolithic PCM CODEC/filters utilizing the A/D and D/A conversion architecture shown inFigure 1, and a serial PCM interface. The devices are fabricated using National’s advanced double-poly CMOS process (microCMOS).
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 m-law or A-law PCM format.
The decode portion of each device consists of an expanding decoder, which reconstructs the analog signal from the companded m-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 3400 Hz followed by a single-ended power amplifier capable of driving low impedance loads.
The devices require two 1.536 MHz, 1.544 MHz or 2.048 MHz transmit and receive master clocks, which may be asynchronous; transmit and receive bit clocks, which may vary from 64 kHz to 2.048 MHz; and transmit and receive frame sync pulses. The timing of the frame sync pulses and PCM data is compatible with both industry standard formats.
