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

MicroLeadFrame™ (MLF) package, a high performance 32-pin

metal-glass QFP package, or in die form.
