Name/Description

54 AGND GND Analog Ground. A common AGND, DGND, SGND plane is highly rec-

ommended.

55 VDD PWR Analog Power Supply.

56 VFXI

I Voice Frequency Transmit Input. This node requires a 10 MΩ or

20 MΩ resistance to AGND. The value is dependent upon the gain of

the XAG amplifier (register 146). 20 MΩ can be used for any gain

setting, 10 MΩ can only be used for XAG gain settings of 0 dB and

+6.02 dB.

57 VFROP O Voice Frequency Receive Output, Positive Polarity. This pin can

drive 2000 Ω (or greater) loads.

58 VFRON O Voice Frequency Receive Output, Negative Polarity. This pin can

drive 2000 Ω (or greater) loads.
