L8560 Low-Power SLIC with Ringing

Lucent Technologies Inc.

Description (continued)

The L8560 product family is graded by different fea-

tures, specifications, and package options. The

L8560Axx is the basic full-feature SLIC that operates

with 5 V and a battery supply, and is available in the

32-pin PLCC (AAU) package and the 44-pin PLCC

package (AP). This part is graded as the 54 dB longitu-

dinal balance part. Additional features (spare op amp

and overhead voltage programming) are available in

the 44-pin PLCC package.

The L8560CAU is available only in the 32-pin PLCC

package and has a feature set similar to the AAU ver-

sion, except the CAU version requires +5 V, –5 V, and

battery power supplies. With this option, power con-

sumption is greatly reduced.

The L8560DAU and L8560EP are available in the

32-pin and 44-pin PLCC packages and have feature

sets identical to the L8560AAU and L8560AP, respec-

tively, with the following modifications. These parts are

graded as high longitudinal balance (63 dB), and have

an additional logic state (scan with low battery) which

allows for low on-hook power dissipation.

The L8560FAU and L8560GP are available in the

32-pin and 44-pin PLCC packages and have feature

sets identical to the L8560AAU and L8560AP, respec-

tively, with the following modifications. These parts are

graded for lower longitudinal balance (50 dB), and

have an additional logic state (scan with battery) which

allows for low on-hook power dissipation.

Table 1 below summarizes the features in the L8560

product family.
