reserves the right to fulfill all orders for this device with

parts marked with the "Am" part number prefix until all inventory

bearing this mark has been depleted. Note that parts marked with

either the "Am" or the "Le" part number prefix are equivalent

devices in terms of form, fit, and function—the prefix appearing on

the topside mark is the only difference.

Due to size constraints, QFN devices are marked by omitting the

“Le” prefix and the performance grade dash character. For

example, Le79R79-1FQC is marked 79R791FQC.

The green package meets RoHS Directive 2002/95/EC of the

European Council to minimize the environmental impact of

electrical equipment.

For delivery using a tape and reel packing system, add a "T" suffix

to the OPN (Ordering Part Number) when placing an order.

DESCRIPTION

The Le79R79 Ringing SLIC device is a bipolar monolithic SLIC

that offers on-chip ringing. Designers can achieve significant

cost reductions at the system level for short-loop applications

by integrating the ringing function on chip. Examples of such

applications would be ISDN terminal adaptors, fiber-in-the-

loop, radio-in-the-loop, hybrid fiber/coax and video telephony

(home-side) boxes. The Le79R79 Ringing SLIC device can

provide sufficient voltage to meet the stringent LSSGR five-

ringer equivalent specification. Using a CMOS-compatible

input waveform and wave shaping R-C network, the Le79R79

Ringing SLIC device can provide trapezoidal wave ringing to

meet various design requirements.

PRODUCT DESCRIPTION

Data Sheet

The

Zarlink

family of subscriber line interface circuit (SLIC) products provide the telephone interface functions required

throughout the worldwide market.

Zarlink

SLIC devices address all major telephony markets including central office (CO), private

branch exchange (PBX), digital loop carrier (DLC), fiber-in-the-loop (FITL), radio-in-the-loop (RITL), hybrid fiber coax (HFC), and

video telephony applications.

The

Zarlink

SLIC devices offer support of BORSHT (battery feed, overvoltage protection, ringing, supervision, hybrid, and test)

functions with features including current limiting, on-hook transmission, polarity reversal, Tip Open, and loop-current detection.

These features allow reduction of linecard cost by minimizing component count, conserving board space, and supporting

automated manufacturing.

The

Zarlink

SLIC devices provide the two- to four-wire hybrid function, DC-loop feed, and two-wire supervision. Two-wire

termination is programmed by a scaled impedance network. Transhybrid balance can be achieved with an external balance circuit

or simply programmed using a companion

Zarlink

codec/filter, such as the Le58QL0xx Quad SLAC (QLSLAC™) device.

The Le79R79 Ringing SLIC device is a bipolar monolithic SLIC that offers on-chip ringing. Now designers can achieve significant

cost reductions at the system level for short-loop applications by integrating the ringing function on chip. Examples of such

applications would be ISDN terminal adaptors, fiber-in-the-loop, radio-in-the-loop, hybrid fiber/coax and video telephony (home-

side) boxes. The Le79R79 Ringing SLIC can provide sufficient voltage to meet the stringent LSSGR five-ringer equivalent

specification. Using a CMOS-compatible input waveform and wave shaping R-C network, the Le79R79 Ringing SLIC can provide

trapezoidal wave ringing to meet various design requirements.

In order to further enhance the suitability of this device in short-loop, distributed switching applications,

Zarlink

has maximized

power savings by incorporating battery switching on chip. The Le79R79 Ringing SLIC device switches between two battery

supplies such that in the off-hook (active) state, a low battery is used to save power. In order to meet the Open Circuit voltage

requirements of fax machines and maintenance termination units (MTU), the SLIC device automatically switches to a higher

voltage in the On-hook (Standby) state.

Like all of the

Zarlink

SLIC devices, the Le79R79 Ringing SLIC device supports on-hook transmission, ring-trip detection,

programmable loop-detect threshold, and is available with on-chip polarity reversal. The Le79R79 Ringing SLIC device is a

programmable constant-current feed device with two on-chip relay drivers to operate external relays. Several performance grades

are available to meet both CCITT and LSSGR requirements, including various longitudinal balance options.
