NAME TCM29C13A TCM129C13A TCM29C14A TCM129C14A TCM29C16A TCM29C17A TCM129C16A TCM129C17A I/O DESCRIPTION PCM IN 8 10 6 I Receive PCM input. PCM data is clocked in on PCM IN on eight consecutive negative transitions of the receive data clock, which is CLKR in fixed-data-rate timing and DCLKR in variable-data-rate timing. PCM OUT 13 16 11 O Transmit PCM output. PCM data is clocked out on PCM OUT on eight consecutive positive transitions of the transmit data clock, which is CLKX in fixed-data-rate timing and DCLKX in variable-data-rate timing. PDN 5 5 4 I Power-down select. The device is inactive with a TTL low-level input to this PDN and active with a TTL high-level input to this PDN. PWRO + 2 2 2 O Noninverting output of power amplifier. PWRO + drives transformer hybrids or high-impedance loads directly in either a differential or a single-ended configuration. PWRO – 3 3 3 O Inverting output of power amplifier. PWRO – is functionally identical with and complementary to PWRO +. SIGR 8 O Signaling bit output, receive channel. In the fixed-data-rate mode, SIGR outputs the logical state of the 8th bit (LSB) of the PCM word in the most recent signaling frame. SIGX/ASEL 15 18 I A-law and µ-law operation select. When connected to VBB, A-law is selected. When connected to VCC or GND, µ-law is selected. When not connected to VBB, it is a TTL-level input that is transmitted as the eighth bit (LBS) of the PCM word during signaling frames on PCM OUT (TCM29C14A and TCM129C14A only). SIGX/ASEL is internally connected to provide µ-law operational for TCM29C16A and TCM129C16A and A-law operation for TCM29C17A and TCM129C17A. TSX/DCLKX 14 17 12 I/O Transmit channel time-slot strobe (output) or data clock (input) for the transmit channel. In the fixed-data-rate mode, TSX/DCLKX is an open-drain output to be used as an enable signal for a 3-state output buffer. In the variable-data-rate mode, DCLKX becomes the transmit data clock, which operates at a TTL level from 64 kHz to 2.048 MHz. VBB 1 1 1 Most negative supply voltage. Input is – 5 V ±5%. VCC 20 24 16 Most positive supply voltage. Input is 5 V ±5%. |
