description
The TP3054A, TP3057A, TP13054A, and
TP13057A are comprised of a single-chip PCM
codec (pulse code-modulated encoder and
decoder) and PCM line filter. These devices
provide all the functions required to interface a
full-duplex (2-wire) voice telephone circuit with a
TDM (time-division-multiplexed) system. These
devices are pin-for-pin compatible with the
National Semiconductor TP3054A and TP3057A,
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 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 TP3054A, TP3057A, TP13054A, and TP13057A provide the band-pass filtering of the
analog signals prior to encoding and after decoding of voice and call progress tones. The TP3057A and
TP13057A contain patented circuitry to achieve low transmit channel idle noise and are not recommended for
applications in which the composite signals on the transmit side are below –55 dBm0.
The TP3054A and TP3057A are characterized for operation from 0
°
C to 70
°
C. The TP13054A and TP13057A
are characterized for operation from –40
°
C to 85
°
C.
These devices have limited built-in 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 MOS gates.
