SY84782U
Low Power 2.5V 1.25Gbps FP/DFB Laser
Diode Driver
General Description
The SY84782U is a single 2.5V supply, ultra-low power,
small form factor laser diode driver for telecom/datacom
applications. Intended to drive FP/DFB lasers at data rates
up to 1.25Gbps, it is especially useful for Compact SFP,
SFP and SFF modules where power requirements are
quite stringent. The driver can deliver modulation current
up to 90mA and offers a high compliance voltage, all of
which make the SY84782U suitable for high current
operations in both AC and DC coupled applications.
The SY84782U is intended to be used with Micrel’s
MIC3003 Optical Transceiver Management IC, which
allows for both modulation and bias current control and
monitoring. Furthermore, the MIC3003 offers power control
and temperature compensation.
This device operates across the industrial temperature
range (–40°C to +85°C) and is available in a small 3mm x
3mm QFN package.
