Detailed Description
The MAX3841 contains a pair of CML inputs that drive
two 2:1 multiplexers, with separate select inputs SEL1
and SEL2, providing a 2
×
2 crosspoint data path. The
outputs of the multiplexers each drive a high-perfor-
mance CML output that can be disabled (powered
down) using the ENO1/ENO2 inputs. All of the data
paths are fully differential to minimize jitter, crosstalk,
and signal skew. See Figure 1 for the functional diagram.
CML Input and Output Buffers
The MAX3841 input and output buffers are terminated
with 50
to independent supply lines, and are also com-
patible with 100
differential terminations. (See Figures 3
and 4.) Separate power-supply connections are provided
for the core, input buffers, and output buffers to allow DC-
coupling to 1.8V, 2.5V, or 3.3V CML ICs. If desired, the
CML inputs and outputs can be AC-coupled.
The CML inputs accept serial NRZ data with differential
amplitude from 150mV
P-P
to 1200mV
P-P
(see Figure 2).
The CML outputs provide 500mV
P-P
nominal differential
swing, resulting in low power consumption.
