Abstract

The invention discloses a wireless communication radio frequency chip structure circuit and a radio frequency control word sending and receiving method, which improves the 3-wire interface of the radio frequency chip and the radio frequency control word sending and receiving method, uses the architecture of two register groups inside the radio frequency chip, and one register group stores The radio frequency control word of the current working time slot, and another register group stores the radio frequency control word of the next working time slot; during the switching time of the two working time slots before and after, through the additional 1 control line and m address lines respectively parallel Send address control words to trigger the value transfer operation between the two memory banks, and these address control words determine the number of register values ​​transferred. Therefore, the configuration speed and configuration flexibility of the radio frequency control word of the radio frequency chip are greatly improved, and the switching time of the communication time slot is satisfied.

Description

Technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a wireless communication radio frequency chip structure circuit and a radio frequency control word transceiving method. Background technique [0002] In the wireless communication terminal, the radio frequency chip needs the baseband chip to serially transmit the radio frequency control word (such as DATA, CLK, LE) in different communication states. figure 1 (Shown), perform operations such as switching the frequency point of the frequency synthesizer, changing the charge pump current, and controlling the internal analog circuit, where the radio frequency chip samples DATA on the rising or falling edge of CLK, and receives the LE signal to trigger the control operation. With the development of RF chips in the direction of low power consumption and multi-function, the corresponding digits and numbers of the RF control words that meet the maximum CLK frequency have inc...
