Interface Schematics
Equivalent Output Interface
The MAX3657 has a differential CML output structure
with 100
back termination (200
differentially). Figure
5 is a simplified diagram of the output interface. The
output current is divided between the internal 100
resistor and the external load resistance. Because of
the CML structure, the maximum output-signal ampli-
tude is affected by load impedance. Note that the inter-
nal back termination is 100
single ended and external
termination is recommended to interface the device to
50
test equipment. For example, if single-ended oper-
ation in a 50
system is required, first match the output
of the MAX3657 to the 50
controlled impedance by
placing a 100
pullup resistor in parallel with the out-
put. Then establish similar loading conditions on the
unused output. Note that the loading conditions affect
the overall gain of the MAX3657. Figures 6a, 6b, and 6c
show alternate interface schemes for the MAX3657.
