CPRI and 10G Ethernet Data Recovery IC

with Amp/EQ from 614.4 Mbps to 10.3125 Gbps

Data Sheet

ADN2905

FEATURES

GENERAL DESCRIPTION

Serial CPRI data rates

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

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

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 an equalizer or a 0 dB EQ as the

input. The equalizer is either adaptive or can be manually set.

I²C to access optional features

Loss of lock (LOL) indicator

PRBS generator/detector

The ADN2905 also supports pseudorandom binary sequence

(PRBS) generation, bit error detection, and input data rate

readback features.

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

The ADN2905 is available in a compact 4 mm × 4 mm, 24-lead

chip scale package (LFCSP). All ADN2905 specifications are

defined over the ambient temperature range of −40°C to +85°C,

unless otherwise noted.

APPLICATIONS

SFF-8431-compatible

Ethernet: 10GE, 1GE, and CPRI: OS/L.6 up to OS/L.96
