ENV
Quadrature modulation signal envelope (
I + Q
Its output level is 500 mVpp with 1.6 Vdc as a center value. The output pin load conditions are:
R
≥
10 k
W
, C
￡
20 pF. The gain of this output can be adjusted using the control registers CR2
- B7 to B4.
This pin is also used to monitor eye pattern, AFC compensating signal, and phase detection of
the demodulator block during the test mode. Refer to the description of the control register for
details.

) output.
BSTO
Modulation burst window signal output.
The burst position for the I/Q baseband modulation output is output. (Refer to Fig. 1.)
