3.11. H/W Sub System

3.11.1. RF Interface
A. RTR6285(WCDMA_Tx, GSM_Tx/Rx)
MSM6260 controls RF part(RTR6285) using these signals.
SBST : SSBI I/F signals for control Sub-chipset
PA_ON1 : Power AMP on RF part
RX0_I/Q_M/P,TX_I/Q_M/P : I/Q for T/Rx of RF
TX_AGC_ADJ : control the gain of the Tx signal prior to the power amplifier
DAC_REF : Reference input to the MSM Tx data DACs
