B E N E F I T S :
Unique architecture provides excellent output impedance, further
reducing output jitter.
Extended case temperature range (-10
C to 95C) 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.

The VSC7983 is a 11.2Gb/s electroabsorption
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 preclude the need for

additional off-chip circuitry. The unique architecture of the
VSC7983 provides excellent output impedance which
improves the match between the driver and load, further
reducing output jitter. The VSC7983 is available in a 32-pin
MicroLeadFrameTM (MLF) package, a high performance 32-pin
metal-glass QFP package, or in die form.
