Bandgap Decouple Voltage. Decoupled N/A

to ground with a 220nF capacitor.

O

Buffered Analog RSSI output with a

nominal sensitivity of 35mV/dB. In analog

test modes, this pin and the AOUT output

become test access points controlled by

the serial control bus.

SERIAL BUS SIGNALS

I (CMOS)

I (CMOS)

Control Bus Enable. Enable pin for the

three-wire serial control bus that sets the

operating frequency and programmable

options. The control registers are loaded

on a low-to-high transition of the signal.

Serial control bus data is ignored when

this signal is high. This is a CMOS input,

and the thresholds are referenced to

VDD and VSS.

Serial Control Bus Data. 16-bit words,

which include programming data and the

two-bit address of a control, register. This

is a CMOS input, and the thresholds are

referenced to VDD and VSS.

Serial control bus data is clocked in on

the rising edge when EN is low. This is a

CMOS input; the thresholds are

referenced to VDD and VSS.
