DESCRIPTION  
RXA  
32  
I
Received modulated analog signal input from the telephone line  
interface.  
TXA1 / TXA2  
18 / 17  
O
Transmit Analog (differential outputs): 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.  
XTL1 / XTL2  
3 / 4  
27  
I
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.  
OH  
O
OFF-HOOK RELAY DRIVER: This signal is an open drain output  
capable of sinking 30mA and is used for controlling a relay. The  
output is the complement of the OH register bit in the ID Register.
