SY88992L
3.3V, 4.25Gbps VCSEL Driver
General Description
Features
The SY88992L is a single supply 3.3V, low power
consumption, small-form factor VCSEL driver ideal
for use in datacom applications; Ethernet, GbE
(Gigabit Ethernet), and FC (Fibre Channel)
applications that operate from 100Mbps up to
4.25Gbps. The modulation current is set by applying
an external voltage at the IM_SET pin. The driver
features an adjustable peaking option with variable
amplitude and duration to improve VCSEL edge
response. The driver can deliver modulation current
up to 25mA and a peaking current up to 35% of the
modulation current. This device is intended to be
used with Micrel’s MIC3001 Optical Transceiver
Management IC, which allows for both modulation
and bias current control and monitoring, APC
(Automatic Power Control), and temperature
compensation.
