((RFREQ)。RFREQ可编程为38位二进制分数频率乘法器,前10位高有效位(MSB)表示乘法器的整数部分,28位低有效位(LSB)表示分数部分。在将分数输入RFREQ寄存器之前,必须使用按位左移操作将其转换为38位整数28位,从而有效地将RFREQ乘以228。示例:RFREQ=46.043042064d将RFREK乘以228=12359584992.1丢弃分数部分=12359594992转换为十六进制=02E0B04CE0h在上面的示例中,乘法运算需要38位精度。如果38位算术精度不可用,则小数部分可以与整数分离,并向左移位28位。结果与整数部分连接以形成完整的38位字。此操作的示例如图4所示。RFREQnew 0x2EBB04CE0 148.50 MHz 148.35 M www.skyworksinc。com Rev.1.6•Skyworks专有信息•产品和产品信息随时可能更改,恕不另行通知•2022年3月4日图4.RFREQ十进制到十六进制转换示例3.1.2.1.在RFREQ的新值出现后写入新频率配置RFREQ). RFREQ is programmable as a 38-bit binary fractional frequency multiplier with the first 10 most significant bits (MSBs) representing the integer portion of the multiplier, and the 28 least significant bits (LSBs) representing the fractional portion. Before entering a fractional number into the RFREQ register, it must be converted to a 38-bit integer using a bitwise left shift operation by 28 bits, which effectively multiplies RFREQ by 228. Example: RFREQ = 46.043042064d Multiply RFREQ by 228 = 12359584992.1 Discard the fractional portion = 12359584992 Convert to hexadecimal = 02E0B04CE0h In the example above, the multiplication operation requires 38-bit precision. If 38-bit arithmetic precision is not available, then the fractional portion can be separated from the integer and shifted to the left by 28- bits. The result is concatenated with the integer portion to form a full 38-bit word. An example of this operation is shown in Figure 4.
