The resistor values for standard operation are selected for an input current of 16
μ
A into the
IL19006, at the rated line current.
The values of these resistors are calculated as follows:
Phase 1:

may be varied within ± 10% for calibration purposes. Any
changes to R 14 + P 14 will affect the output quadratically
(i.e:
R = +5%,
f = +10%).

XTAL is a colour burst TV crystal (f = 3.5795 MHz) for the oscillator. The oscillator
frequency is divided down to 1.78975 MHz on-chip, to supply the digital circuitry and the A/D
converters.
