L9500B

High-Voltage Ringing SLIC for VoIP Applications

L9500B Introduction

The Agere Systems Inc. L9500B is a subscriber line inter-

face circuit (SLIC) that is optimized for short-loop, power-

sensitive applications. This device provides the complete

set of line interface functionality (including power ringing)

needed to interface to a subscriber loop. This device has

the capability to operate with a

Vcc

supply of 3.3 V or 5 V

and is designed to minimize external components

required at all device interfaces. This device is optimized

to interface to data over cable service interface specifica-

tion (DOCSIS) compliant cable modem gateway, to a mul-

timedia adaptor, and to residential gateway products,

such as the

Broadcom

BCM3351, BCM3352,

BCM6352, and BCM1101 and equivalent products.

Applications

Interface to

Broadcom:

— BCM3351 cable modem

— BCM3352 cable modem

— BCM6352 integrated multimedia adaptor

— BCM1101 residential gateway

Features

Description

This device is optimized to provide battery feed, ringing,

and supervision on short-loop plain old telephone service

(POTS) loops.

This device provides power ring to the subscriber loop

through amplification of a low-voltage input. It provides

forward and reverse battery feed states, on-hook trans-

mission, a low-power scan state, ground start (tip open),

and a forward disconnect state.

The device requires a

Vcc

and battery to operate.

Vcc

may be either a 5 V or a 3.3 V supply. The ringing signal

is derived from the high-voltage battery. A battery switch

is included to allow for use of a lower-voltage battery in

the off-hook mode, thus minimizing short-loop off-hook

power.

Maximum operating battery voltage is –85 V. This will

extend the ringing loop length. It also increases ringing

peak-to-peak voltage for improved compatibility with CPE

and allows for lighting of neon lamps that can be associ-

ated with various CPE.

Loop closure, ring trip, and ground start detection is avail-

able. The loop closure detector has a fixed threshold with

hysteresis. The ring trip detector requires a single-pole fil-

ter, thus minimizing external components required.

The dc current limit is set and fixed by a logic-controllable

pin. Ground or open applied to this pin sets the current

limit at the low or high value.

The device is offered with differential ringing and receive

input, making it ideal for direct interface to DOCSIS com-

pliant cable modem gateway products.

Differential ringing and codec interface

Three ringing input options:

— Sine wave

— PWM

— Logic level square wave

Onboard ringing generation

Three ringing input options:

— Sine wave

— PWM

— Logic levels

— Square wave

Flexible

Vcc

options:

— 5 V or 3.3 V

Vcc

— No –5 V required

Battery switch to minimize off-hook power

Eight operating states:

— Scan mode for minimal power dissipation

— Forward and reverse battery active

— On-hook transmission states

— Ground start

— Ring mode

— Disconnect mode

Ultralow on-hook power:

— 30 mW scan mode

— 42 mW active mode

Loop start, ring trip, and ground start detection

Software-controllable dual-current limit option
