description  
DW OR N PACKAGE  
(TOP VIEW)  
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:

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.
