HXT5112A
Short Form Datasheet
12 Channel 14Gb/s VCSEL Driver
Description
Features
The HXT5112A VCSEL driver array is a key
component for compact, robust and low-power
optical transmitter modules. In conjunction with
the VCSEL array, the chip handles the complete
digital-to-optical conversion, including CML
input, laser driver, drive control and supervision.
Standard silicon technology and a small number
of additional components allow for cost-
effective and compact assemblies.
• Low-power consumption of 46mW per
channel while delivering 5mA average and
5mA modulation current
• Compatible with common cathode and
isolated VCSEL arrays
• 2-wire interface control and symmetric pad
design maximize module design flexibility
• 10mA average and 10mA modulation current
maximum
• 15mA burn-in current maximum
• InfiniBand QDR/FDR compliant
• 100G Base-SR10 compliant
Typical Applications
• IEEE 802.3ba Ethernet transceivers
• Infiniband QDR & FDR active cables
• Proprietary multi-channel optical modules
• Solder bump version available
