Figure 35: Phone Control dialog box

2. Select the following values on the RF Main Mode dialog box:.

19.2 MHZ VCTCXO Reference Clock

The VCTCXO frequency is a 19.2MHz reference signal. Without 19.2MHz, the phone does

not power up. This signal goes to Batman, Jupiter, the UHF PLL, and also to the UPP. Use

a high impedance probe to check for the presence of the signal at the following points:

• F_REF_TX, clock reference to Jupiter, should be ~ -9 dBm

• F_REF_RX, clock reference to Batman, should be ~ -9 dBm

• CLK10M2_UPP, clock reference to UPP, should be ~ -9 dBm and ~2 dB less in the

other side on R517
