ADN2913ACPZ-RL7

Continuous Rate 6.5Mbps to 8.5Gbps Clock and Data Recovery IC with Integrated Limiting Amp/EQ

Product Details

The ADN2913 provides the receiver functions of quantization, signal level detection, and clock and data recovery for continuous data rates from 6.5 Mbps to 8.5 Gbps. The ADN2913 automatically locks to all data rates without the need for an external reference clock or programming. ADN2913 jitter performance exceeds all jitter specifications required by SONET/SDH, including jitter transfer, jitter generation, and jitter tolerance.

The ADN2913 provides manual or automatic slice adjust and manual sample phase adjusts. Additionally, the user can select a limiting amplifier, equalizer, or 0 dB EQ at the input. The equalizer is adaptive or it can be manually set.

The receiver front-end loss of signal LOS detector circuit indicates when the input signal level falls below a user-programmable threshold. The LOS detection circuit has hysteresis to prevent chatter at the LOS output. In addition, the input signal strength can be read through the I2C registers.

The ADN2913 also supports pseudorandom binary sequence PRBS generation, bit error detection, and input data rate readback features.

The ADN2913 is available in a compact 4 mm × 4 mm, 24-lead lead frame chip scale package LFCSP. All ADN2913 specifications are defined over the ambient temperature range of −40°C to +85°C, unless otherwise noted.
