1.4 Pin Description

Note: The signal and pin names prefixed by # in this manual are those of active-low signals and pins.

Table 1.4.1 Pin description

Pin name Pin No. Type Power-down

status Description

INP 1 Input

Analog Off/

Active + Input: Non-inverting amplifier input. This pin is connected to the

telephone wire through an input gain-setting resistor and a DC cut

capacitor. Under the power downmode, this pin is functionary

disconnected from the internal circuitry when the MODE1 pin is set to

low level. When the MODE1 pin is set to high level, this pin stays

active to detect FSK signal energy to send wake up signal to the host

through the #IRQ pin. Do not connect any external components to this

pin except gain setting resistors to this pin. Excess load may cause

improper operation of the circuit.

INN 2 Input

Analog Off/

Active - Input: Inverting amplifier input. This pin is connected to the

telephone wire through an input gain-setting resistor and a DC cut

capacitor. Under the power downmode, this pin is functionary

disconnected from the internal circuitry when the MODE1 pin is set to

low level. When the MODE1 pin is set to high level, this pin stays

active to detect FSK signal energy to send wake up signal to the host

through the #IRQ pin. Do not connect any external components to this

pin except gain setting resistors to this pin. Excess load may cause

improper operation of the circuit.

FB 3 Output

Analog High-Z/

Active Amplifier Output: A feed back resistor is connected between this pin

and the INN pin to set gain. Under the power down mode, this output

pin is set to high impedance when the MODE1 pin is set to low level.

When theMODE1 pin is set to high level in power down, this pinstays

active to detect FSK signal energy to send wake up signal to the host

through the #DET pin. Do not connect any external components to

this pin except a gain setting resistor to this pin. Excess load may

cause improper operation of the circuit.

CASIN 4 Input

Analog Off CAS Tone Input: CAS tone amplifier input. For the telephone

application, this pin is connected to the output of telephone hybrid

circuit through input gain-setting resistor and a DC cut capacitor.

Under the power down mode,this pin is functionary disconnected

from the internal circuitry. Do not connect any external components to

this pin except gain setting resistors to this pin. Excess load may

cause improper operation of the circuit.

CASFB 5 Output

Analog High-Z CAS Amplifier Output: A feed back resistor is connected between

this pin and the CASIN pin to set CAS gain. Under the power down

mode, this output pin is set to high impedance. Do not connect any

external components to this pin except a gain setting resistor to this

pin. Excess load may cause improper operation of the circuit.

VREF 6 Output

Analog High-Z/

VDD/2 level Reference Voltage Output: 1/2 VDD voltage output. This pin must be

bypassed to ground through 0.1 µF capacitor. During power down

mode, this output pin is set to high impedance when the MODE1 pin

is low level. When theMODE1 pin is set to high level in power down,

this pin stays at VDD/2. Do not connect any external components to

this pin except a jumper to VREF pin or a bypass capacitor to ground.

Excess load may cause improper operation of the circuit.

EXTREF 7 Input

Analog Active External Reference Voltage Input: External DC reference voltage is

connected to this pin. This voltage set the off-hook detectionthreshold

level.

output

Schmitt

trigger input

Active Ring Detect RC Terminal: RC network will be connected to this pin

to set time delays for the ring signal detection. This circuit is always

active even if the device is in the power down mode.

#RDET 11 Output Active Ring Detect Output: When theMODE1 pin is set to low level,thispin

is connected from output of a Schmitt trigger buffer which input is

connected to the#RDRC pin. Low level at this pin indicates that the

ring signal is detected. When the MODE1 pin bit is set to high level,

this pin is connected from output of a hook detect circuit which input is

connected from the HOOK pin. High level at this pinindicateson-hook

condition and low level at this pin indicates off-hook condition.

PDWN 12 Input Active Power Down Input: This pin must be kept at low level for the normal

operation. When it is set to high level, the device enters the power

down mode. During power down mode, the OSC4 pin is set to high

level, and the VREF, CASFB and FB pins are set to high impedance.

(The FB and VREF pins are set to high impedance only whenthe

MODE1 pin is at low level.)

#RESET 13 Input Active Reset Input: When this pin is set to low level, all internalhost

registers are reset to their default conditions.This pin must be set to

high level to write data to the internal registers.

VSS 14 Power

supply (-) Device Ground: This pin is connected to the system ground.

OSC3 15 Input Off Crystal Oscillator/External Clock Input: A crystal resonator is

connected between this pin and the OSC4 pin. This pin may be driven

from an external clock source. The proper value load capacitor must

be connected between this pin and ground. During power down, this

input pin is disconnected from internal circuits.

OSC4 16 Output High level Crystal Oscillator Output: A crystal or ceramic resonator is

connected betweenthis pin and OSC3 pin. Thispin must be kept

open when the OSC3 pin is driven from an external clock source. The

proper value load capacitor must be connected between this pin and

ground. During power down, this output pin is set to high level.

EXTCLK 17 Input Active External Clock Input: Typically 32.768 kHz clock signal is applied to

this pin from the host device to enable pre-qualification logic used in

FSK energy detection circuitry.

MODE0 18 Input Active Mode0 Select Input: This pin select CAS or FSK/CPM mode. When

this pin is set to high level, CAS mode is selected. In this mode, CAS

detection is enabled and the FSK function is disabled. The host

device also can write internal registers through the SDI and #SCLK

pin. Before writing data into registers, this pin must be set to low level

once to synchronize theserial interface circuit for data writing

sequence. When this pin is set to low level, FSK/CPM mode is

selected. In this mode, CAS detection is disabled and the FSK/CPM

function is enabled. The host device also can read the received data

from the SDO pin under this mode. Refer to Table 3.2.1 for more

details.

MODE1 19 Input Active Mode1 Select Input: This pin enables FSK energy and off-hook

detection mode. When this pin is set to high level, FSK energy and

off-hook detection mode is enabled. When this pin is set to low level,

FSK energy and off-hook detection mode is disabled. Refer to Table

3.2.1 for more details.

#PQUAL 20 Output High level Pre-qualification Output: Early qualification output will be monitored

at this pin. When no tones are detected, this pin stays at high level.
