3.3V, 2.7Gbps SDH/SONET

LASER DRIVER WITH AUTOMATIC

POWER CONTROL

Micrel, Inc.

SY88952L

FEATURES

DESCRIPTION

■ Single 3.3V power supply

■ Up to 2.7Gbps operation

■ Rise/Fall times: < 75ps

SY88952L is a highly integrated and programmable

laser driver for SONET/SDH application up to 2.7Gbps.

The device accepts differential PECL or LVDS data and

clock inputs. It provides programmable bias and

modulation currents for driving a laser. The modulation

output of SY88952L can be DC-coupled to drive the laser

diode, providing a significant power saving over AC-

coupled operation. A synchronizing TTL input latch can

be used to reduce jitter if a clock signal is available. A

TTL enable is also incorporated in the device. EN only

■ Independent programmable laser modulation and

bias currents

■ Bias current to 100mA and modulation current to

90mA

■ Automatic average laser power control

■ Bias and modulation current monitors

■ Operating temperature range of –40°C to +85°C

enables/disables I

. It does not enable/disable I

MOD

BIAS

An automatic power controller (APC) is integrated into

SY88952L to maintain a constant average optical output

power over temperature and lifetime. The modulation

current can be externally temperature compensated to

minimize the variation of extinction ratio of the optical

output.

■ Complies with ANSI, ITU, and Bellcore SDH/SONET

specifications

■ Available in DIE form and 32-pin (5mm × 5mm)

EPAD-MLF™ package

Several safety features will enable an alarm function

when the output signal is too high, or bias current is too

high.

APPLICATIONS

■ OC-48 transceivers and transponders

■ SONET/SDH transmission system

■ Add drop mux

There are two alarm conditions:

1. /FAIL asserts when bias current loop goes to

maximum of it's range. I
