Available in Bare Dice, 32-pin 5mm x 5mm QFN, or
32-pin Metal-glass QFP
APPLICATIONS:
10G Transmit Optical Sub-Assemblies
- 9.983 Gb/s SONET OC-192/SDH STM-64
- 10.3 Gb/s Ethernet
- 10.5 Gb/s Fibre Channel
- 10.7 Gb/s OTN G.709/G.975

BENEFITS:
Unique architecture provides excellent output impedance, further
reducing output jitter.
Extended case temperature range (-10°C to 95°C) providing more
thermal margin for system design.
Guaranteed operation at worst-case duty cycle (85% crossing point),
improving yield by enabling the use of a wider range of modulators.
Internal operational amplifiers reduce off-chip circuit complexity and
component count.
Output enable for both eye safety and low power in sleep modes
required by new module MSAs.

VSC7984
11.3 Gb/s Electroabsorption Modulator Driver
www.DataSheet4U.com
GENERAL DESCRIPTION:
The VSC7984 is a 11.3Gb/s clocked
modulator driver for SONET/SDH and
10GbE applications. The device provides
selectable data retiming to improve jitter
performance and controls for output bias
voltage, modulation voltage, and duty
cycle. Internal operational amplifiers and on-chip voltage
reference preclude the need for additional off-chip circuitry to
stabilize modulation and offset voltages. A temperature
monitor output indicates temperature to simplify testing and
to verify the device is not operated beyond its recommended
maximum temperature. The VSC7984 is available in a 4mm x
4mm 24-lead plastic package, or in die form.
