DESCRIPTION

Received modulated analog signal input from the telephone

line interface.

(differential) Transmit Analog. These pins provide the analog

output signals to be transmitted to the telephone line. The

drivers will differentially drive the impedance of the line

transformer and the line matching resistor. An external hybrid

can also be built using TXA1 as a single ended transmit

signal.

These pins are for the internal crystal oscillator requiring a

11.0592 MHz parallel mode crystal. Load capacitors should

be connected from XTL1 and XTL2 to ground. XTL2 can also

be driven from an external clock.

OFF-HOOK RELAY DRIVER: This signal is an open drain

output capable of sinking 40 mA and is used for controlling a

relay. The output is the complement of the OH register bit in

the ID Register.
