11 / 16 page —11— CXA3038N PLL circuit (when Pin 21 is connected to VCC) • A PLL is formed by connecting the anode of the LC parallel resonance circuit varicap diode to the Pin 18 output via a high resistance of approximately 10 k Ω and connecting a loop filter between Pin 18 and Pin 19. • The PLL circuit consists of a main divider, reference divider, phase comparator, charge pump, and reference oscillator. • The frequency dividing data is included in the main divider, making external data settings unnecessary. • The reference frequency has been designed at 50 kHz. • Fine adjustment of the VCO frequency can be performed by changing the frequency dividing value of the main divider through an applied voltage to Pin 12. This allows adjustment in ±4 steps at 50 kHz intervals based at 479.5 MHz as shown in the table below. • The reference divider has two types of frequency dividing data, 80 and 200. • Either 4 MHz or 10 MHz can be selected for the crystal oscillator. When using the 4 MHz crystal oscillator, opening Pin 3 will select a frequency dividing value of 80 for the reference divider, and the reference frequency will become 50 kHz. In the same way, when using the 10 MHz crystal oscillator, connecting Pin 3 to GND will select a frequency dividing value of 200 for the reference divider, and the reference frequency will become 50 kHz. This is summarized in the table below. Pin 12 voltage [V] 0.597 VCC or more 0.517VCC to 0.595VCC 0.438VCC to 0.515VCC 0.358VCC to 0.436VCC 0.279VCC to 0.356VCC 0.199VCC to 0.277VCC 0.120VCC to 0.197VCC 0.042VCC to 0.118VCC 0 to 0.04VCC Frequency dividing value 9594 9593 9592 9591 9590 9589 9588 9587 9586 VCO oscillation frequency [MHz] 479.70 479.65 479.60 479.55 479.50 479.45 479.40 479.35 479.30 Crystal oscillator 4 MHz 10 MHz Pin 3 voltage Open 0.8 V or less Frequency dividing value of the reference divider 80 200 Reference frequency 50 kHz 50 kHz |
