Selecting a Clock Crystal
Choose a 27MHz parallel resonant, fundamental mode
crystal. No external load capacitors are needed. All
capacitors required for the Pierce oscillator are includ-
ed on-chip.
Power Supply and Bypassing
The MAX7456 operates from three independent supply
lines. Each supply must be within a +4.75V to +5.25V
voltage range. Separate the digital power supply from
the analog and video-driver supply lines to prevent
high-frequency digital noise that may couple onto the
video output. All three supplies should be at the same
DC voltage. Bypass each supply with a 0.1μF capacitor
to ground very close to the IC pins. There are no
power-supply sequencing requirements for the device.
Layout Concerns
For best performance, make the VIN and VOUT traces
as short as possible. Place all AC-coupling capacitors
and 75
termination resistors close to the device with
the resistors terminated to the solid analog ground
plane. Since the MAX7456 TSSOP package has an
exposed pad (EP) underneath, do not run traces under
the package to avoid possible short circuits. Refer to
the MAX7456 EV kit for an example of PCB layout.
To aid heat dissipation, the EP should be connected to
a similarly sized pad on the component side of the
PCB. This pad should be connected through to the sol-
der-side copper by several plated holes to conduct
heat away from the device. The solder-side copper pad
area should be larger than the EP area. It is recom-
mended that the EP be connected to ground, but it is
not required. Do not use EP as the only ground connec-
tion for the device.
