TP3052, TP3053, TP3054, TP3057, Enhanced Serial Interface CODEC/Filter COMBO Family

The TP3054 TP3057 family consists of ?-law and A-law monolithic PCM CODEC Filters utilizing the A/D and D/A conversion architecture shown in Figure 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 ?-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 ?-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.
