The MAX4567 has two V+ and two V- pins. Make DC
connections to only one of each to minimize crosstalk.
Do not route DC current into one of the V+ or V- pins
and out the other V+ or V- pin to other devices. The
second set of V+ and V- pins is for AC bypassing only.
For dual-supply operation, the MAX4567 should have
four 10nF bypass capacitors connected to each V+
and V- pin as close to the package as possible. For sin-
gle-supply operation, the MAX4567 should have two
10nF bypass capacitors connected (one to each V+
pin) as close to the package as possible.
On the MAX4565, GND5 and GND6 should always be
connected to the ground plane with solid copper to
improve isolation and crosstalk.
S ignal Routing
Keep all signal leads as short as possible. Separate all
signal leads from each other and other traces with the
ground plane on both sides of the board. Where possible,
use coaxial cable instead of printed circuit board traces.
Board Layout
IC sockets degrade high-frequency performance and
should not be used if signal bandwidth exceeds 5MHz.
Surface-mount parts, having shorter internal lead
frames, provide the best high-frequency performance.
Keep all bypass capacitors close to the device, and
separate all signal leads with ground planes. Such
grounds tend to be wedge-shaped as they get closer to
the device. Use vias to connect the ground planes on
each side of the board, and place the vias in the apex of
the wedge-shaped grounds that separate signal leads.
Logic-level signal lead placement is not critical.
