DALLAS, TEXAS 75265
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 TCM129C13, TCM129C14, TCM129C16, TCM129C17, TCM29C13, TCM29C14, TCM29C16, and
TCM29C17 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.
The TCM29C13, TCM29C14, TCM29C16, and TCM29C17 are characterized for operation from 0
°
C to 70
°
C.
The TCM129C13, TCM129C14, TCM129C16, and TCM129C17 are characterized for operation from –40
°
C
to 85
°
C.
