LV2700V

Pin Functions

Pin No.

1

Pin

RFVCC

Pin voltage(V)

Pin function

RF block power supply

2

REXT

0.2

Connection for the external capacitor and resistor

used by the internal RF amplifier

3

RFIN

4

RFGND

1

RF input

RF block ground

5 ANTDUMP

Output for the DC voltage used under strong

1.2

reception conditions to prevent saturation of the

RF amplifier.

Voltage variability range: about 0.5 V

6

RXVCC

Reception block power supply

7

BIASIN

DC bias voltage for the demodulation signal

processing block (LPF, amplifier, limiter)

Equivalent circuit

8

RXOUT

Demodulated data output

(This is an open drain output.)

9 LOCK DET

Outputs a high level when PN code

synchronization is established.

(This is a CMOS-level output.)

10

CEXT

Same as

V7

Amplifier output for demodulated output.

The pin 8 output data is made valid by connecting

a capacitor between this pin and ground.
