MAX3748HETE+T

MAXIM INTEGRATED PRODUCTS  MAX3748HETE+T  限幅放大器, 155Mbps至4.25Gbps, 2.97 V, 3.63 V, TQFN, 16 引脚, -40 °C

The is a compact, low power, 155Mbps to 4.25Gbps limiting amplifier in 16 pin TQFN package. The MAX3748H limiting amplifier consists of an input buffer, a multistage amplifier, offset correction circuitry, an output buffer, power-detection circuitry and signal detect circuitry. This multirate limiting amplifier functions as a data quantizer for SONET, fibre channel and gigabit Ethernet optical receivers. The amplifier accepts a wide range of input voltages and provides constant-level current-mode logic output voltages with controlled edge speeds. A received signal strength indicator RSSI is available when the MAX3748H is combined with the MAX3744 SFP transimpedance amplifier. A receiver consisting of the MAX3744 and the MAX3748H can provide up to 19dB RSSI dynamic range. Additional features include a programmable loss of signal detect, an optional disable function and an output signal polarity reversal. Output disable can be used to implement squelch.
