3.10 H/W Sub System
3.10.1 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 ESM Tx data DACs
