I/O I/O Type

Signal Name/Description

DIB INTERFACE

O

Odpc

Clock and Power Positive. Provides clock and power to the LSD. Connect to

DIB transformer primary winding non-dotted terminal.

O

Odpc

Clock and Power Negative. Provides clock and power to the LSD. Connect to

DIB transformer primary winding dotted terminal.

I/O

Idd/Odd Data Positive. Transfers data, control, and status information between HSD

and LSD. Connect to LSD through DIB data positive channel components.

I/O

Idd/Odd Data Negative. Transfers data, control, and status information between HSD

and LSD. Connect to LSD through DIB data negative channel components.

TELEPHONE LINE (DAA)/AUDIO INTERFACE

O

Ot2

Modem Reset. Connect to VC POR pin.

O

Ot2

Master Clock Output. Connect to VC M_CLKIN pin.

O

Ot2

Voice Control Output. Connect to VC M_CNTRLSIN pin.

I

Itpd

Voice Serial Clock input. Connect to VC M_SCK pin.

I

It

Voice Serial Receive Data Input. Connect to VC M_RXOUT pin.

O

Ot2

Voice Serial Transmit Data Output. Connect to VC M_TXSIN pin.

I

Itpd

Voice Serial Frame Sync Input. Connect to VC M_STROBE pin.

O

Ot2

Modem Sleep. Connect to VC SLEEP pin.

O

Ot12

Voice Relay Control. Output (typically active low) used to control the normally

open voice relay. The polarity of this output is configurable.

I/O

It/Ot12

Speaker Mute/Vaux Mode Power Select. Output (typically active low) used to

turn off (mute) the speaker during normal operation. Applicable to S models

only.

Upon device reset, this pin is temporarily an input and is sampled. If sampled

high and VauxDET is high, VpciEN# will be asserted when the device is in D0.

If sampled low (e.g., SPKMUTE signal is pulled down to GND through 10k Ω)

and VauxDET is high, VauxEN# will be asserted when the device is in D0.

VauxEN# is always asserted when VauxDET is high in D3 with PME enabled.

Either VauxEN# or VpciEN#, but not both, can be asserted at the same time.

O

Ot12

Call Progress (Digital Speaker) Output. The DSPKOUT digital output reflects

the received analog input signal digitized to TTL high or low level by an internal

comparator. This signal is used for call progress or carrier monitoring. This

output can be optionally connected to a low-cost on-board speaker, e.g., a

sounducer, or to an analog speaker circuit.

I

Itpu

Binary Audio Input. Binary audio source.
