Micro Linear ML6622

The ML6622 high-speed data quantizer (post-amplifier) is a low noise, wide-band, BiCMOS monolithic IC designed for high-speed signal recovery applications, such as FDDI, Fast Ethernet, and ATM. The limiting amplifier contributes to a high level of sensitivity and a minimum of duty cycle distortion. The output of the data path is a high-speed comparator with ECL outputs.

GENERAL DESCRIPTION

An internal DC restoration feedback loop nulls any offset voltage produced in the input stage. An enable pin gates the comparator on or off in response to the input signal level or a system control signal. The Link Detect circuit provides an Assert-Deassert function with a user-selectable threshold voltage. This circuit monitors the input signal and provides an ECL High output within 100ms of signal acquisition and an ECL Low output within 350ms of signal loss. The ECL discriminator output can be used to disable the comparator when the signal is below the user-selected threshold. LINKLED drives an LED for a visible indication of the link status.
