Description
This general-purpose electronic subscriber loop
interface circuit (SLIC) is optimized for low cost, while
still providing a satisfactory set of features. This part
is a pin-for-pin replacement for the Agere L9217 and
L9218 SLICs.
The L9219 requires a 5 V power supply and single
battery to operate. This device offers forward and
reverse battery operation. The rate of battery rever-
sal may be ramped to meet international require-
ments. Additionally, a low-power scan mode, wherein
all circuitry except the off-hook supervision is shut
down to conserve power, is available.
The dc current limit may be programmed via a single
external resistor. Via the logic table, the current limit
may be increased a nominal 42% above the value
set by the IPROG resistor, giving the user a high-low
current limit option.
Device overhead is fixed and is adequate for
3.14 dBm into 900
of on-hook transmission.
Both the loop supervision and ring trip supervision
functions are offered with user-controlled thresholds
via external resistors.
The L9219 is offered with a receive gain that is opti-
mized for interface to a first-generation type codec
(L9219A). It is also offered with a gain option that is
optimized for interface to a third- or fourth-generation
type codec (L9219G). In both cases, minimizing
external components required at this interface.
Data control is via a parallel data control scheme.
The device is available in a 28-pin PLCC package. It
is built by using a 90 V complementary bipolar
(CBIC) process.
