description
The TP3064B, TP3067B, TP13064B, and
TP13067B each comprise a single-chip pulse-
code-modulation encoder and decoder (PCM
codec), and PCM line filter. They also provide
band-pass filtering of the analog signals prior to
the encoding, and low-pass filtering after the
decoding of voice signals and call-progress tones.
All the functions required to interface a full-duplex
(2-wire) voice telephone circuit with a time-divi-
sion-multiplexed (TDM) system are included
on-chip. These devices are pin-for-pin compatible
with the National Semiconductor TP3064 and
TP3067. Primary applications include:
Line interface for digital transmission and
switching of T1 carrier, PABX (private
automated branch exchange), 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, and are intended to be used
at the analog termination of a PCM line or trunk. They require a transmit master clock and a receive master clock
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 TP3064B and TP13064B 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.
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 CMOS gates.
