ADN2813ACPZ
Continuous Rate 10 Mb/s to 1.25 Gb/s Clock and Data Recovery IC with Integrated Limiting Amp ADN2813 Data Sheet FEATURES GENERAL DESCRIPTION Serial data input: 10 Mb/s to 1.25 Gb/s Exceeds SONET requirements for jitter transfer/ generation/tolerance Quantizer sensitivity: 3.3 mV typ Adjustable slice level: ±95 mV Patented clock recovery architecture Loss-of-signal (LOS) detect range: 2.3 mV to 19 mV Independent slice level adjust and LOS detector No reference clock required Loss-of-lock indicator I2C® interface to access optional features Single-supply operation: 3.3 V Low power: 450 mW typ 5 mm × 5 mm 32-lead LFCSP, Pb free The ADN2813 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 10 Mb/s to 1.25 Gb/s. The ADN2813 automatically locks to all data rates without the need for an external reference clock or programming. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for −40°C to +85°C ambient temperature, unless otherwise noted. This device, together with a PIN diode and a TIA preamplifier, can implement a highly integrated, low cost, low power fiber optic receiver. The receiver front-end, loss-of-signal (LOS) detector circuit indicates when the input signal level has fallen below a useradjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output. APPLICATIONS SONET OC-1/-3/-12 and all associated FEC rates Fibre Channel, GbE, HDTVs WDM transponders Regenerators/repeaters Test equipment Broadband cross-connects and routers The ADN2813 is available in a compact 5 mm × 5 mm, 32-lead LFCSP.
