DATOUT<8:7>:

bit 8

bit 7

: Demodulated Output

: Carrier Clock Output

: RSSI Output

• Configuration Register 2 (Register 5-3),

RSSIFET<8>:

: Pull-Down MOSFET off

are affected.

FIGURE 5-8:

RSSI Output Path.

Note:

The pull-down MOSFET option is valid

only when the RSSI output is selected.

The MOSFET is not controllable by users

when demodulated or carrier clock output

option is selected.
