The ADN2892 is a 4.25 Gbps limiting amplifier with integratedloss of signal (LOS) detection circuitry and a received signalstrength indicator (RSSI). This part is optimized for FibreChannel (FC) and Gigabit Ethernet (GbE) optoelectronicconversion applications. The ADN2892 has a differential inputsensitivity of 3.5 mV p-p and accepts up to a 2.0 V p-pdifferential input overload voltage. The ADN2892 has currentmode logic (CML) outputs with controlled rise and fall times.The ADN2892 has a selectable low-pass filter with a −3 dBcutoff frequency of 1.5 GHz. By setting BW_SEL to Logic 0, thefilter can limit the relaxation oscillation of a low cost CD laserused in a legacy 1 Gbps FC transmitter. The limited BW alsoreduces the rms noise and in turn improves the receiver opticalsensitivity for a lower data rate application, such as 1× FC andGbE.By monitoring the bias current through a photodiode, the onchipRSSI detector measures the average power received with2% typical linearity over the entire valid input range of thephotodiode. The on-chip RSSI detector facilitates SFF-8472-compliant optical transceivers by eliminating the need forexternal RSSI detector circuitry.Additional features include a programmable loss-of-signal(LOS) detector and output squelch. The ADN2892 is availablein a 3 mm × 3 mm, 16-lead LFCSP.Applications 1×, 2×, and 4× FC transceivers  SFP/SFF/GBIC optical transceivers  GbE transceivers  Backplane receivers

ADP7104 20 V, 500 mA, Low Noise, CMOS LDOThe ADP3334 is a member of the ADP333x family of precision low dropout anyCAP® voltage regulators.
