ML4621CQ中文资料MICRO-LINEAR数据手册PDF规格书

GENERAL DESCRIPTION

The ML4621 data quantizer is a low noise, wideband monolithic IC designed specifically for signal recovery applications in fiber-optic receiver systems. It contains a two stage wideband limiting amplifier which is capable of accepting an input signal as low as 2mV with a 55dB dynamic range. This high level of sensitivity is achieved by using a DC restoration feedback loop which nulls any offset voltage produced in the limiting amplifier.

FEATURES

■ 50MHz minimum bandwidth for data rates of up to 100MBd

■ Can be powered by either 5V providing TTL level outputs, or -5.2V providing ECL level outputs

■ Low noise design: 25µV RMS over 50MHz noise bandwidth

■ Adjustable link monitor function

■ Wide 55dB input dynamic range

■ 10ns minimum input pulse
