Table 7. AD8370 Evaluation Board Configuration Options
Component
Function
Default Condition
VS, GND, VOCM
Power Interface Vector Pins. Apply supply voltage between VS and GND. The VOCM
pin allows external monitoring of the common-mode input and output bias levels.
Not applicable
SW1, R8,
C10, PWUP
Device Enable. Set to Position B to power up the device. When in Position A, the PWUP
pin is connected to the PWUP vector pin. The PWUP pin allows external power cycling
of the device. R8 and C10 are provided to allow for proper cable termination.
SW1 = installed
R8 = 49.9 (Size 0805)
C10 = open (Size 0805)
P1, R5, R6,
R7, C9
Serial Control Interfaces. The evaluation board can be controlled using most PCs.
Windows-based control software is shipped with the evaluation kit. A 25-pin, D-sub
connector cable is required to connect the PC to the evaluation board. It may be
necessary to use a capacitor on the clock line, depending on the quality of the PC port
signals. A 1 nF capacitor for C9 is usually sufficient for reducing clock overshoot.
P1 = installed
R5, R6, R7 = 1 k (Size 0603)
C9 = open (Size 0603)
J1, J2, J6, J7
Input and Output Signal Connectors. These SMA connectors provide a convenient way
to interface the evaluation board with 50 test equipment. Typically, the device is
evaluated using a single-ended source and load. The source should connect to
J1 (IN+), and the load should connect to J6 (OUT+).
Not applicable
C1, C2, C3, C4
AC Coupling Capacitors. Provide ac coupling of the input and output signals.
C1, C2, C3, C4 = 1 nF (Size 0603)
T1, T2
Impedance Transformers. T1 provides a 50 to 200 impedance transformation.
T2 provides a 100 to 50 impedance transformation.
T1 = TC4 1W (Mini-Circuits)
T2 = JTX210T (Mini-Circuits)
R1, R2, R3, R4
Single-Ended or Differential. R2 and R4 are used to ground the center tap of the
secondary windings on transformers T1 and T2. R1 and R3 should be used to ground
J2 and J7 when used in single-ended applications.
R1, R2, R3, R4 = 0 (Size 0603)
C5, C6, C7,
C8 L1, L2
Power Supply Decoupling. Nominal supply decoupling consists of a ferrite bead
series inductor followed by a 1 F capacitor to ground followed by a 0.1 F capacitor
to ground positioned as close to the device as possible. C7 provides additional
decoupling of the input common-mode voltage. L1 provides high frequency
isolation between the input and output power supply. L2 provides high
frequency isolation between the analog and digital ground.
C6 = 1 F (Size 0805)
C5, C7, C8 = 0.1 F (Size 0603)
L1, L2 = HZ1206E601R-00
(Steward, Size 1206)
