SY84402L
SY84402L is 4.25Gbps VCSEL Driver manufactured by Micrel Semiconductor.
Description
Features
The SY84402L is a 3.3V VCSEL driver for applications up to 4.25Gbps. The driver es 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.
- 3.3V power supply
- Operates from 100Mps up to 4.25Gbps
- 100k-patible PECL/ECL I/O
- Guaranteed operation over
- 40°C to +85°C temperature range
- Fully controllable with Micrel MIC300X controller
- Available in ultra-small 10-pin MLF® (2mm x 2mm) package
Applications
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 Ohm resistor. The VT pin should be used only as a bias for this device as its current sink/source capability is limited.
- Multirate LAN, SAN applications up to 4.25Gbps: Ethernet, Gb E, FC
- SFF, SFP Modules
- Backplane receiver
