description
The TP3054B, TP3057B, TP13054B, and
TP13057B are comprised of a single-chip
pulse-code-modulated encoder and decoder
(PCM codec) and PCM line filter. These devices
provide all the functions required to interface a
full-duplex (2-wire) voice telephone circuit with a
time-division-multiplexed (TDM) system. These
devices are pin-for-pin compatible with the
National Semiconductor TP3054B and TP3057B,
respectively. Primary applications include:
Line interface for digital transmission and
switching of T1 carrier, PABX, and central
office telephone systems
Subscriber line concentrators
Digital-encryption systems
Digital voice-band data-storage systems
Digital signal processing
These devices are designed to perform the transmit encoding (A/D conversion) and receive decoding (D/A
conversion) as well as the transmit and receive filtering functions in a pulse-code-modulated (PCM) system.
They are intended to be used at the analog termination of a PCM line or trunk. The devices require two transmit
and receive master clocks that may be asynchronous (1.536 MHz, 1.544 MHz, or 2.048 MHz), transmit and
receive data clocks that are synchronous with the master clock (but can vary from 64 kHz to 2.048 MHz), and
transmit and receive frame-sync pulses. The TP3054B, TP3057B, TP13054B, and TP13057B provide the
band-pass filtering of the analog signals prior to encoding and after decoding of voice and call progress tones.
The TP3054B and TP3057B are characterized for operation from 0
°
C to 70
°
C. The TP13054B and TP13057B
are characterized for operation from –40
°
C to 85
°
C.
Caution: These devices have limited built-in gate ESD protection. The leads should be shorted together or the device placed in
conductive foam during storage or handling to prevent electrostatic damage to the CMOS gates.
