3.125Gb/s CML Limiting Amplifier with LOS Detect
Applications
• SONET/SDH at 622Mb/s, 1.244Gb/s, 2.488Gb/s,
and 3.125Gb/s
• Full-Speed Fibre Channel (1.062Gb/s)

General Description
The VSC7959 is a single supply limiting amplifier with Loss of Signal (LOS) detect for SONET/SDH and
Fibre Channel applications up to 3.125Gb/s. The VSC7959 provides a constant output signal swing for a wide
range of input voltages and has Current-Mode Logic (CML) outputs. The VSC7961 provides the same function-
ality as the VSC7959 with positive emitter-coupled logic (PECL) outputs. Key features of the VSC7959 are its
RMS power detectors for programmable LOS detection, optional output squelch, adjustable output levels,
excellent jitter performance, and fast edge rates. The VSC7959 is available in die form or in a TSSOP-16 pack-
age.
