3.11. H/W Sub System
3.11.1. RF Interface
A. RTR6275(WCDMA_Tx, GSM_Tx/Rx)
MSM6280 controls RF part(RTR6275) 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
