Description
The Zarlink ZL49200 Dual SLIC hybrid provides an
interface between a switching system and a subscriber
loop with 600 impedance. The functions provided by
each SLIC include battery feed, 2 W to 4 W
conversion, off-hook and dial pulse detection. All driver
electronics are included on the hybrid in order to
minimize the number of external components required
by the user.

Positive supply rail. +5 V
Ground. Return path for +5 V and -5 V. This should also be connected back to the return
path for the loop battery, Cap and relay drive ground RLYGND.
Negative supply rail. -5 V
Battery Voltage for powering the line
Reference Voltage (Input). This pin is used to set the subscribers loop constant current.
Changing the input voltage sets the current to any desired value within the working limits.
Relay voltage source. Voltage source for relay driver.
