This two-part paper develops novel methodologies for using fractional programming (FP) techniques to design and optimize communication systems. Part I of this paper proposes a new quadratic transform for FP and treats its application for continuous optimization problems. In this Part II of the paper...
The theory presented in Part I (Wen in J. Optim. Theory Appl. 2012) of this study led to a theoretical parametric procedure for continuous-time generalized fractional programming problems. In this paper (Part聽II), an interval-type computational procedure by combining the parametric method and ...
(EQ 14) fout = fVCO 2 = 1402.5 MHz + 0.596 Hz error (EQ 15) In this example the output frequency of 1402.5 MHz is achieved by programming the 19-bit binary value of 56d = 38h into intg_reg in Reg 03h, and the 24-bit binary value of 1677722d = 19999Ah into frac_reg in ...
Required PLL/VCO Settings and Register Write Sequence Configure the PLL registers as described in the PLL Frequency Programming section to achieve the desired frequency, and the last write must be to Register 0x1200 (INT_L). When Register 0x1200 is programmed, an internal VCO calibration ...

After exiting low-power mode, allow at least 20ms for external capacitors to charge to their final values before programming the final VCO frequency. Reference Input The reference input stage is configured as a CMOS inverter with shunt resistance from input to output. In shutdown mode this ...
The CDCM6208V1F can be easily configured through I2C or SPI programming interface and in the absence of serial interface, pin mode is also available that can set the device in 1 of 32 distinct pre-programmed configurations using control pins. Device Information(1) PART NUMBER PACKAGE BODY SIZE...
