MSM7582/7582B

ENV

I²+ Q²

Quadrature modulation signal envelope (

)output.

Its output level is 500 mV with 1.6 Vdc as a center value. The output pin load conditions are

: R ≥ 10 kW, C ≤ 20 pF. The gain of this output can be adjusted using the control register CR2 – B7

to B4.

This pin is also used to monitor eye pattern, AFC Compensating signal, and phase defection of

the demodulator block during the test mode. Refer to the description of the control register for

details.

Internal reference voltage output.

The output voltage is about 2.0 V. A bypass capacitor should be connected between this pin and

the AGND pin.

PDN0, PDN1, PDN2

Inputs for power-down control.

PDN0 controls the standby / communication modes, PDN1 controls the modulator, and PDN2

controls the demodulator. Refer to Table 1 for details.

+3 V power supply voltage.

AGND

Analog signal ground.

DGND

Digital signal ground.

AGND and DGND are not connected in the device. This pin should be tied to the AGND pin on

the PCB as close as possible from the device.
