ADN2905

Data Sheet CPRI and 10G Ethernet Data Recovery IC with Amp/EQ from 614.4 Mbps to 10.3125 Gbps ADN2905 FEATURES GENERAL DESCRIPTION Serial CPRI data rates 614.4 Mbps, 1.2288 Gbps, 2.4576 Gbps, 3.072 Gbps, 4.9152 Gbps, 6.144 Gbps, and 9.8304 Gbps Ethernet data rates: 1.25 Gbps and 10.3125 Gbps No reference clock required Jitter performance superior to the SFF-8431 jitter specifications Optional equalizer or 0 dB EQ input mode Quantizer sensitivity: 200 mV p-p typical (equalizer mode) Sample phase adjust (5.65 Gbps or greater) Output polarity invert I2C to access optional features Loss of lock (LOL) indicator PRBS generator/detector Application aware power 349.5 mW at 9.8304 Gbps, 0 dB EQ input mode 287.7 mW at 6.144 Gbps, 0 dB EQ input mode 249.3 mW at 3.072 Gbps, 0 dB EQ input mode Power supply: 1.2 V, flexible 1.8 V to 3.3 V, and 3.3 V 4 mm × 4 mm, 24-lead LFCSP APPLICATIONS The ADN2905 provides the receiver functions of quantization and multirate data recovery at 614.4 Mbps, 1.2288 Gbps, 1.25 Gbps, 2.4576 Gbps, 3.072 Gbps, 4.9152 Gbps, 6.144 Gbps, 9.8304 Gbps, and 10.3125 Gbps, used in Common Public Radio Interface (CPRI) and gigabit Ethernet applications. The ADN2905 automatically locks to all the specified CPRI and Ethernet data rates without the need for an external reference clock or programming. The ADN2905 jitter performance exceeds the jitter requirement specified by SFF-8431. The ADN2905 provides manual sample phase adjustment. Additionally, the user can select ...
