Device Overview

Summary

The SY84402L is a 3.3V VCSEL driver for applications up to 4.25Gbps. The driver comes in a 2mm x 2mm MLF®package which makes it less than half the size of any other driver operating at that rate. The variable output swing on the SY84402L makes it ideal for use as a VCSEL driver as well as a backplane driver/receiver.

The operational range of the SY84402L control input is from VCC-1.42V (for maximum output swing) to VCC (for minimum output swing). VCTRL can also be driven by a DAC such as those contained in the MIC300X, Micrel's FOM controller family.

The SY84402L provides a VT output for use as a DC bias for AC-coupling to the device. The input termination network can easily be modified to handle a DC-coupled PECL output to save board space by simply tying the VT terminal to ground through a 50 Ω resistor. The VT pin should be used only as a bias for this device as its current sink/source capability is limited.
