MAX3645 - 125Mbps to 200Mbps Limiting Amplifier

General Description

The MAX3645 limiting amplifier functions as a data quantizer and is pin compatible with the Mindspeed MC2045-2 and MC2045-2Y postamplifiers.

Key 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. Features o Pin Compatible with the Mindspeed MC2045-2/MC2045-2Y o 500µV Input Sens.

www.DataSheet4U.com 19-3026; Rev 0; 10/03 +2.97V to +5.5V, 125Mbps to 200Mbps Limiting Amplifier with Loss-of-Signal Detector General Description The MAX3645 limiting amplifier functions as a data quantizer and is pin compatible with the Mindspeed MC2045-2 and MC2045-2Y postamplifiers. 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 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.
