PCB Layout
As with any high speed, mixed-signal design, keep all high
speed digital traces away from sensitive analog nodes.
Figure 21 shows the recommended PCB layout. The 50 Ω
transmission lines are the traces that bring the high frequency
input and output signals (PIN, NIN, OUTP, and OUTN) to the
SMA connectors with minimum reflection. To avoid a signal
skew between the differential traces, each differential PIN/NIN
and OUTP/OUTN pair should have matched trace lengths from
the signal pins to the corresponding SMA connectors. C1, C2,
C3, and C4 are ac coupling capacitors in series with the high
speed, signal input/output paths. To minimize the possible
mismatch, the ac coupling capacitor pads should be the same
width as the 50 Ω transmission line trace width. To reduce
supply noise, a 1 nF decoupling capacitor should be placed on
the same layer as close as possible to the VCC pins. A 0.1 μF
decoupling capacitor can be placed on the bottom of the PCB
directly underneath the 1 nF capacitor. All high speed, CML
outputs have internal 50 Ω resistor termination between the
output pin and VCC. The high speed inputs, PIN and NIN, also
have the internal 50 Ω termination to an internal reference
voltage.
Soldering Guidelines for the LFCSP
The lands on the 16-lead LFCSP are rectangular. The PCB pad
for these should be 0.1 mm longer than the package land length
and 0.05 mm wider than the package land width. The land
should be centered on the pad. This ensures that the solder joint
size is maximized. The bottom of the LFCSP has a central
exposed pad. The pad on the printed circuit board should be at
least as large as the exposed pad. Users must connect the
exposed pad to VEE using filled vias so that solder does not
leak through the vias during reflow. This ensures a solid
connection from the exposed pad to VEE.
