VSC7964
1/2/4 Gbps Integrated VCSEL Driver and Limiting Amplifier
G E N E R A L D E S C R I P T I O N :
The VSC7964 is a multirate 4.25 Gbps integrated
with SFP-compliant fault indicators, redundant disable control,
Automatic Power Control, temperature sensor, voltage reference,
various signal monitors, and robust eye safety features. A single
bidirectional pin between the VSC7964 and the VSC7977
transimpedance amplifier programs the receiver bandwidth and
monitors the received optical power. This allows the VSC7964 to
provide an accurate indicator of received power and to select the
TIA bandwidth without increasing TO-CAN pin count. The VSC7964
is available in a 6mm x 6mm 40-pin QFP-N plastic package.
Vertical Cavity Surface Emitting Laser (VCSEL)
driver and limiting amplifier for Gigabit
Ethernet and Fibre Channel applications
optimized to reduce SFP module cost. A
standard SPI port is provided for programming integrated
digital-to-analog converters for laser bias current, modulation
current, power, modulation peaking current, and the limiting
amplifier loss of signal threshold. The VSC7964 is equipped
