ADN2890ACPZ-RL7

ANALOG DEVICES  ADN2890ACPZ-RL7  限幅放大器, 3 V, 3.6 V, LFCSP, 16 引脚, -40 °C

The is a high gain Limiting Amplifier optimized for use in SONET, Gigabit Ethernet GbE and fibre channel optical receivers that accept input levels of up to 2.0Vp-p differential and have 3mVp-p differential input sensitivity. The ADN2890 provides the receiver functions of quantization and loss of signal LOS detection. The ADN2890 can easily operate at up to 3.2Gb/s to support LX4 transceivers. The limiting amplifier also measures average received power based on a direct measurement of the photodiode current with better than 1dB of accuracy over the entire input range of the receiver. This eliminates the need for external average Rx power detection circuitry in SFF-8472 compliant optical transceivers.
