Modulator Driver
GENERAL DESCRIPTION:
The VSC5529 is a precision LiNbO3 modulator driver. The input can be driven single-ended or
differentially and features a single-ended sensitivity of 250mV. The VSC5529 provides a high
quality single-ended output with amplitude control, precision amplitude monitoring circuitry,
and eye crossing point control. The VSC5529 provides a digital limiting amplifier function to
ensure high quality and very repeatable output signal characteristics even with less than
optimal input signals. Key specifications include ultra-small form factor, fast rise/fall times,
low output jitter, high voltage drive capability, high input sensitivity and low rail ripple.
Furthermore, the VSC5529 amplitude control feature is specifically designed to provide
consistent output shape and crossing point over the full range of control.
