Control Data Format and Description

Reference divider divisor setting data

• The circuit consists of a fixed divide-by-two circuit and a 12-bit reference divider.

• A divisor, which is a multiple of 2 with a value of up to 8190, can be set by sending the reference divider data.

• The value of the divisor is determined as follows.

Divisor N = 2 (R0 + R1 × 21+ R2 × 22+ R3 × 23+ ······+ R11 × 211)

Programmable divider divisor setting data

• The circuit consists of a 4-bit swallow counter and a 10-bit programmable counter.

• A divisor with a value in the range 240 to 16,383 can be set by sending the swallow counter and programmable counter data.

• The value of the divisor is determined as follows.

Divisor N = (16D + A)

D = P4 + P5 × 21+ P6 × 22+ P7 × 23+ ······ + P13 × 2

A = P0 + P1 × 21+ P2 × 22+ P3 × 2

PLL Divisor Setup Example

• The reference divider divisor is calculated as follows when a 12.8 MHz crystal element is used, the comparison frequency in the phase detector is 5 kHz, and the VCO oscillator frequency is 26.545 MHz.

12.8 MHz ÷ 5 kHz = 2560 (divisor value)

Since there is a fixed divide-by-two circuit, the required divisor is as follows.

2560 × 1/2 = 1280

The value 1280 converted to binary (10100000000) is the reference divider setting data. The programmable divider divisor is calculated as follows.

26.545 MHz ÷ 5 kHz = 5309 (divisor value)

The value 5309 converted to binary (1010010111101) is the programmable divider setting data.

• The control data is set as follows
