ADN2905

• Full featured evaluation board for the ADN2905/ADN2913/ADN2915/ADN2917
• Configurable as PRBS generator or PRBS error detector
• Locked to any rate, continuous mode, up to 11.3 Gbps input signal

The ADN2905, ADN2913, ADN2915, and ADN2917 provide the receiver functions of quantization, signal level detect, and clock/data recovery for a continuous signal data rate range from 6.5 Mbps to 11.3 Gbps. The ADN29xx automatically lock to such a data signal without referring to an external clock or extra programming. All SONET/SDH jitter requirements are exceeded, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for the –40°C to +85°C temperature range, unless otherwise noted.

For the best input signal detection, the ADN29xx input circuitry can be configured as a limiting amplifier, an equalizer, or a 0 dB equalizer. Additionally, the ADN29xx provide manual control of sampling phase and slice level adjust to optimize the incoming data eye detection.

The loss of signal (LOS) is available in limiting amplifier input mode only. The asserted LOS indicates that the input signal level has fallen below a preset threshold. The LOS detect circuit provides a typical 6.0 dB hysteresis to prevent LOS output chatter.

The asserted loss of lock (LOL) indicates when incoming signal rate shifts more than 1000 ppm away from the CDR VCO frequency.

The ADN29xx are available in a compact 4 mm × 4 mm, 24-lead chip scale package (LFCSP).

Full specifications on the ADN2905/ADN2913/ADN2915/ADN2917 are available in the product data sheet, which should be consulted in conjunction with this user guide when working with the evaluation board.

The ADN2905, ADN2913, ADN2915, and ADN2917 are pin-to-pin compatible devices and share the same evaluation board. Each EVALZ-ADN29xx evaluation board is populated by a different DUT: ADN2905 on the EVALZ-ADN2905, ADN2913 on the EVALZ-ADN2913, ADN2915 on the EVALZ-ADN2915, and ADN2917 on the EVALZ-ADN2917.
