description (continued)
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 system. They are
intended to be used at the analog termination of a PCM line or trunk.
The TCM29C13A, TCM29C13A, TCM29C16A, TCM29C17A, TCM129C13A, TCM129C14A, TCM129C16A,
and TCM129C17A provide the band-pass filtering of the analog signals prior to encoding and after decoding.
These combination devices perform the encoding and decoding of voice and call progress tones as well as the
signaling and supervision information. These devices 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 TCM29C13A, TCM29C14A, TCM29C16A, and TCM29C17A are characterized for operation from 0

C to
70
°
C. The TCM129C13A, TCM129C14A, TCM129C16A, and TCM129C17A are characterized for operation
from –40
