GENERAL DESCRIPTION
The ADN29xx (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 (see Table 1). 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.
