Pin Configuration
Layout Considerations
The inputs and outputs are critical paths for the
MAX3679, and care should be taken to minimize dis-
continuities on these transmission line. Here are some
suggestions for maximizing the MAX3679’s perfor-
mance:
An uninterrupted ground plane should be posi-
tioned beneath the clock I/Os.
Ground pin vias should be placed close to the IC
and the input/output interfaces to allow a return
current path to the MAX3679 and the receive
devices.
Supply decoupling capacitors should be placed
close to the MAX3679 supply pins.
Maintain 100
Ω differential (or 50Ω single-ended)
transmission line impedance out of the MAX3679.
Use good high-frequency layout techniques and a
multilayer board with an uninterrupted ground
plane to minimize EMI and crosstalk.
Refer to the MAX3679 Evaluation Kit for more information.
Exposed-Pad Package
The exposed pad on the 32-pin TQFN package pro-
vides a very low inductance path for return current trav-
eling to the PCB ground plane. The pad is also
electrical ground on the MAX3679 and must be sol-
dered to the circuit board ground for proper electrical
performance.
