and tested to demonstrate the specified high speed performance

of the device. Figure 51 shows the schematic of the evaluation

board. T he silkscreen for the component side layer is shown in

Figure 52. T he layout of the board is shown in Figure 53 and

Figure 54.

As already mentioned, the AD8320 has a dynamic output im-

pedance of 75 Ω. T he specified gain range assumes that the

output is terminated with a 75 Ω load impedance. Varying the

load impedance allows the gain to be varied, up to a maximum

of twice the specified gain (for R_L

= ϱ). T he variation in gain

T he evaluation board package includes a fully populated board

with BNC-type connectors along with Windows^®-based soft-

ware for controlling the board from a PC’s printer port via a

standard printer cable.

with load resistance is shown in Figure 50 for the case of a gain

control word of 255Dec (i.e., max gain).

A prototyping area is provided to allow for additional circuitry

on the board. The single supply and ground to the board are

brought over to this area and are available on two strips. T here

are also two extra strips available on the prototyping area which

can be used for additional power supplies.

T he board should be powered with a good quality (i.e., low

noise) single supply of between +5 V and +12 V. Extensive

decoupling is provided on the board. A 10 µF capacitor, located

fairly close to the device, provides good decoupling for lower

frequency signals. In addition, and more importantly, five

0.1 µF decoupling capacitors are located close to each of the

five power supply pins (7, 8, 9, 17 and 20).

T he evaluation board ships with Windows-based control soft-

ware. A standard printer cable can be used to connect the

evaluation board to a PC’s printer port (also called parallel

port). T he cable length should be kept to less than about 5 feet.

T he wiring of a standard printer cable, with respect to the sig-

nal lines that are used in this application, is shown in Figure 55.

Although the software controls the evaluation board via the

PC’s parallel port, the AD8320 digital interface is serial. T hree

of the parallel port’s eight bits (and one digital ground line) are

used to implement this serial interface. A fourth bit is used to

control the PD pin.

Figure 50. Gain vs. R_LOAD(Gain Control Word = 255Dec)

T he gain can be described by the following equation:

2 R_LOAD

A_V= 20 log₁₀

R_LOAD+75

where Code is the decimal equivalent of the 8-bit word.
