VSC7984
11.3 Gb/s Electroabsorption Modulator Driver
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.
