Description

1, 4

VPOS

Positive Supply Voltage, 2.7 V to 5.5 V.

2

INHI

RF Input. AC-coupled RF input.

3

INLO

RF Common for INHI. AC-coupled RF common.

5, 6, 7, 8,

13, 15, 16

NC

No Connect. These pins can be left open or be soldered to a low impedance ground plane.

9

TADJ

Temperature Compensation Adjustment. Frequency-dependent temperature compensation is set by

applying a specified voltage to the pin. The TADJ pin has dual functionality as a power-down pin, PWDN.

Applying a voltage of V

10

COMM

Device Common.

11

VSET

Setpoint Input for Operation in Controller Mode. To operate in RSSI mode short VSET to VOUT.

12

VOUT

Logarithmic/Error Output.

14

CLPF

Loop Filter Capacitor Pin. In measurement mode, this capacitor pin sets the pulse response time and video

bandwidth. In controller mode, the capacitance on this node sets the response time of the error

amplifier/integrator.

15 (EPAD)

Exposed Paddle

(EPAD)

Internally connected to COMM; solder to a low impedance ground plane.
