MAX3969ETP+

MAXIM INTEGRATED PRODUCTS  MAX3969ETP+  限幅放大器, PECL数据输出, 2.97 V, 5.5 V, TQFN, 20 引脚, -40 °C

The is a 200Mbps SFP limiting amplifier with PECL data outputs in 20 pin TQFN package. It is ideal for low cost ATM, fast Ethernet, FDDI and ESCON fibre optic receivers. The device has 1mVP-P input sensitivity and an integrated power detector that senses the input signal power. It provides a received signal strength indicator RSSI which is an analogue indication of power level. Signal strength is also indicated by complementary TTL loss of signal LOS outputs and the PECL signal detect SD output both of which indicate power level relative to a programmable threshold. The threshold can be adjusted to detect signal amplitudes as low as 2.7mVP-P. An optional squelch function disables switching of data outputs by holding them at a known state when the signal is below programmed threshold. The MAX3969 is used in SFP/SFF transceivers, 155Mbps LAN ATM transceivers and FTTx transceivers.
