BASIC CONNECTIONS
Figure 58 shows the basic connections for the AD8335. Input
signals enter from the left and output signals exit from the right,
providing straight line signal paths. Of course, a device with
four differential VGAs such as this requires a multilayer printed
circuit board. Power supply isolation is shown for the preamps,
and for the VGA sections. If components are mounted to both
sides of the board, those in the signal path should be located on
the top, with power-supply decoupling components on the
wiring side.
PREAMP CONNECTIONS
To configure the AD8335 for input matching, a feedback resistor
(RFB) is ac-coupled between Pin PONx and Pin PIPx. AC coupling
accommodates dissimilar common-mode voltages at the input
and output ports. For values of RSOURCE between 50 Ω and 200 Ω,
RFB is simply 5 × RSOURCE. Table 6 lists a few larger values of source
resistor (or RIN), along with the exact value and nearest standard
1% feedback resistor. For values other those than listed in Table 6,
RFB can be calculated using Equation 6. For values larger than
1 kΩ, it may be advantageous to simply remove RFB.
