This datasheet provides a comprehensive overview of the ADN2892's features, including input sensitivity, 70ps rise/fall times, CML outputs, bandwidth, LOS output, programmable LOS detector, Rx signal strength indicator (RSSI), SFF-8472 compliant average power measurement, single-supply operation, low power dissipation, and compact 16-lead LFCSP package.
The ADN2892 is a 3.3 V, 4.25 Gbps limiting amplifier designed for Fibre Channel (FC) and Gigabit Ethernet (GbE) optoelectronic conversion applications. It features integrated loss-of-signal (LOS) detection circuitry and a received signal strength indicator (RSSI), eliminating the need for external components in many designs.
The device includes a selectable low-pass filter with a -3 dB cutoff frequency of 1.5 GHz to support multirate modules (1x, 2x, or 4x FC). It operates from a single 3.3 V supply with low power dissipation and is available in a space-saving 3 mm x 3 mm, 16-lead LFCSP package.
