Typical Application Circuits continued at end of data sheet.
Pin Configuration appears at end of data sheet.
The MAX3969 limiting amplifier with PECL data outputs is
ideal for low-cost ATM, Fast Ethernet, FDDI and ESCON
fiber optic receivers.
The MAX3969 features 1mV
integrated power detector that senses the input signal
power. It provides a received-signal-strength indicator
(RSSI), which is an analog indication of the power level.
Signal strength is also indicated by the complementary
TTL loss-of-signal (LOS) outputs and the PECL signal-
detect (SD) output, both of which indicate the power
level relative to a programmable threshold.
The threshold can be adjusted to detect signal ampli-
tudes as low as 2.7mV
disables switching of the data outputs by holding them
at a known state when the signal is below the pro-
grammed threshold.
The MAX3969 is available in die form and a 4mm x
4mm, 20-pin thin QFN package.
