3.0 Functional Description
3.1
Overview
The M02040-15 is a high-gain limiting amplifier for applications up to 2.125 Gbps and incorporates a limiting ampli-
fier, an input signal level detection circuit and also a fully integrated DC-offset cancellation loop that does not
require any external components. The M02040-15 features PECL data outputs.
The M02040-15 provides the user with the flexibility to set the signal detect threshold. Optional output buffer dis-
able (squelch/jam) can be implemented using the JAM input.
