General Description
The MAX3992 is a 10Gbps clock and data recovery
(CDR) with equalizer IC for XFP optical transmitters. The
MAX3992 and the MAX3991 (CDR with limiting amplifier)
form a signal conditioner chipset for use in XFP trans-
ceiver modules. The chipset is XFI compliant and offers
multirate operation for data rates from 9.95Gbps to
11.1Gbps.
The MAX3992 recovers the data for up to 12 inches of
FR-4 and one connector without the need for a stand-
alone equalizer. The phase-locked loop is optimized for
jitter tolerance in SONET, Ethernet, and Fibre-Channel
applications. Low jitter generation of 4mUIRMS leaves
adequate margin for meeting SONET jitter requirements
at the optical output.
An AC-based power detector asserts the loss-of-signal
(LOS) output when the input signal is removed. An exter-
nal reference clock, with frequency equal to 1/64 or 1/16
of the serial data rate, is used to aid in frequency acqui-
sition. A loss-of-lock (LOL) indicator is provided to indi-
cate the lock status of the receiver PLL.
The MAX3992 is available in a 4mm x 4mm, 24-pin QFN
package. It consumes 356mW from a single +3.3V sup-
ply and operates over a 0°C to +85°C temperature range.
