BSTO
BSTO is the modulator side burst output position specification signal.
The burst time and position of the I and Q analog output including the lamp bits are output. (Refer
to Fig. 3)
I+, I–
Quadrature modulation signal I Component differential analog output.
Their output levels are 500 mVPP (maximum) with 1.6 Vdc as the center value. The output pin
load conditions are: R ≥ 10 kW, C ≤ 20 pF. The gain of these pins can be adjusted using the control
register CR15 - B7 to B4, and the offset voltage at the I– pin can be adjusted using CR16 - B7 to
B3.
Q+, Q–
Quadrature modulation signal Q component differential analog outputs.
Their output levels are 500 mVPP (maximum) with 1.6 Vdc as the center value. The output pin
load conditions are: R ≥ 10 kW, C ≤ 20 pF. The gain of these pins can be adjusted using the control
register CR15 - B7 to B4, and the offset voltage at the Q– pin can be adjusted by using CR17 - B7
to B3.
SGM
MODEM internal reference voltage output.
The output voltage value is approximately 2.0 V. Insert a bypass capacitor of approximately 0.1
mF between this pin and the AGM pin.
The SG voltage if necessary should be used via a buffer.
