General Description
The VSC7961 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 VSC7961 provides a constant output signal swing for a wide
range of input voltages and has Positive Emitter-Coupled Logic (PECL). The VSC7959 provides the same func-
tionality as the VSC7961 with Current-Mode Logic (CML) outputs. Key features of the VSC7961 are its RMS
power detectors for programmable LOS detection, optional output squelch, adjustable output levels, excellent
jitter performance, and fast edge rates. The VSC7961 is available in die form or in a TSSOP-16 package.
