Detailed Description and
Applications Information
Figure 1 is a functional diagram of the MAX3971A limit-
ing amplifier. The signal path consists of an input buffer
followed by a gain stage and output amplifier. A feed-
back loop provides offset correction by driving the
average value of the differential output to zero.
Gain Stage and Offset Correction
The limiting amplifier provides approximately 42dB
gain. The large gain makes the amplifier susceptible to
small DC offsets, which cause deterministic jitter. A
low-frequency loop is integrated into the limiting ampli-
fier to reduce output offset, typically to less than 2mV.
The external capacitor (CZ) is required for stability and
to set the low-frequency cutoff for the offset correction
loop. The time constant of the loop is set by the product
of an equivalent 20k
Ω on-chip resistor and the value of
the off-chip capacitor (CZ). For stable operation, the
minimum value of CZ is 0.01F. To minimize pattern-
dependent jitter, CZ should be as large as possible.
For 10Gbps ethernet and SONET applications, the typi-
cal value of CZ is 0.1F. Keep CZ close to the package
to reduce parasitic inductance.
CML Input Circuit
The input buffer is designed to accept CML input sig-
nals such as the output from the MAX3970 transimped-
ance amplifier. An equivalent circuit for the input is
shown in Figure 2. For lowest deterministic jitter in all
operating conditions, AC-coupling capacitors are rec-
ommended on the input.
