Re-timing

Laser Driver

GD16521

an Intel company

Preliminary

General Description

Features

The GD16521 is a high performance low

power 2.5 Gbit/s Laser Driver with

optional on chip re-timing of data.

laser diode. A modulation current control

loop maintains a constant modulation

current for the laser diode, or alterna-

tively maintains a constant extinction ra-

tio of the laser diode.

Differential CML data and clock

inputs with internal 50 W load termi-

nation.

The GD16521 is designed to meet and

exceed ITU-T STM-16 and SONET

OC-48 fiberoptic communication systems

requirements.

Selectable on chip retiming-FF.

Re-timing of the data signal connected to

the pins SDIP/SDIN is made by means of

a DFF-clocked by an external clock sig-

nal at the data rate fed to the pins SCIP/

SCIN.

Output modulation current pulse duty

width adjustable

(Compensates for LD emission delay)

The GD16521 is designed to sink a Mod-

ulation Current into the IM pin and a

Pre-Bias Current into the IB pin. The

Modulation Current is adjustable up to

50 mA and the Pre-Bias Current is ad-

justable up to 100 mA. The device fea-

tures two control loops for stabilizing the

laser diode operating conditions. An au-

tomatic optical power control loop main-

tains a constant average optical power

out of the laser diode, independent of

changes in the threshold current of the

Modulation/Bias current monitor

output.

The GD16521 requires a single +3.3 V

supply.

Modulation/Bias current shutdown

input.

The circuit is available as:

48 lead 7 × 7 mm TQFP power

enhanced plastic package

die.

Single supply operation: +3.3 V.

Power dissipation: 410 mW (typ.).
