Analog Devices ADN2917 Continuous Rate Clock & Data Recovery IC is designed to provide the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 8.5-11.3Gbps. ADN2917 automatically locks to all data rates without requiring an external reference clock or programming. ADN2917's performance exceeds all jitter specifications required by SONET/SDH, including jitter transfer, jitter generation, and jitter tolerance. The design also provides manual or automatic slice adjust and manual sample phase adjusts. Additionally, the designer can select a limiting amplifier or equalizer at the input. The equalizer is either adaptive or can be manually set. The receiver front-end loss of signal (LOS) detector circuit shows when the input signal level has fallen below a user-programmable threshold. The LOS detect circuit uses hysteresis to prevent chatter at the LOS output. In addition, the input signal strength can be read through the I²C registers. ADN2917 also supports pseudorandom binary sequence (PRBS) generation, bit error detection, and input data rate readback features. The ADN2917 is available in a compact 4mm × 4mm, 24-lead frame chip scale package (LFCSP). All ADN2917 specifications are defined over the ambient temperature range of −40°C to +85°C. Applications include SONET/SDH OC-192, 10GFC, 10GE & all associated FECs, XFP, line cards, clocks, routers, repeaters, instruments, and any rate regenerators/repeaters.
