The MAX3645EEE+T is a +2.97V to +5.5V, 125Mbps to 200Mbps limiting amplifier with loss of signal detector in 16 pin QSOP package. The limiting amplifier functions as a data quantizer and is pin compatible with the Mindspeed MC2045-2 and MC2045-2Y post amplifiers. The amplifier accepts a wide range of input voltages and provides constant-level positive emitter-coupled logic (PECL) output voltages with controlled edge speeds. The MAX3645EEE+T 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.
