L7585F Full-Feature, Low-Power SLIC and Switch

Features

Description

■ Low active power

The L7585F Full-Feature, Low-Power Subscriber

Loop Interface Circuit (SLIC) and Switch integrates

the battery feed, test access relay, and ringing relay

that are necessary to interface a codec to the tip and

ring of a subscriber loop into one low-power, low-cost

package. It is built using a 90 V complementary bipo-

lar (CBIC) process and a 320 V Bipolar-CMOS-

DMOS (BCDMOS) process. The device is available

in a 44-pin PLCC package.

■ Quiet tip/ring polarity reversal

■ Distortion-free on-hook transmission

■ 35 V to 60 V power supply operation

■ 14 operating states:

— Forward battery active

— Reverse battery active

— Ground start (3)

— Forward battery ring open

— Reverse battery ring open

— Reverse battery tip open

— High impedance

The device can be connected directly to the Agere

Systems Inc. T8531/T8532 16-Channel Programma-

ble Codec Chip Set without the need for any ac inter-

face components.

— Ringing (2)

— Low current (2)

— Disconnect

■ Self-test in all operating states

■ Independent, adjustable ac and dc parameters:

— Switchhook detector threshold

— Loop current limit

— dc feed resistance

— Termination impedance

■ Integrated ringing access relay

■ Integrated test-in relay

■ Integrated relay driver

■ Integrated ring trip detector

■ Thermal protection

■ 44-pin, surface-mount, plastic package (PLCC)
