16-QSOP
Lead Free Status / RoHS Status
Lead free / RoHS Compliant
The MAX3645 limiting amplifier functions as a data
quantizer and is pin compatible with the Mindspeed
MC2045-2 and MC2045-2Y postamplifiers. The amplifi-
er accepts a wide range of input voltages and provides
constant-level positive emitter-coupled logic (PECL)
output voltages with controlled edge speeds.
The MAX3645 features an integrated power detector
with complementary PECL loss-of-signal (LOS) outputs
that indicate when the input power level drops below a
programmable threshold. An optional squelch function
holds the data outputs at static levels during a
LOS condition.
The MAX3645 operates from a single +3.3V or +5.0V
power supply over a -40°C to +85°C temperature
range. It is available in 16-pin SO and 16-pin QSOP
packages.
