Description

16 XTAL

2.0

16MHz crystal is needed for PLL

6

reference frequency. If external clock is

injected to Pin 16, frequency should be

14

from 1MHz to 24MHz and N (integer) ×

200kHz.

When the IC is Standby mode, external

clock should be stop.

Usually pin 19 should be kept “Logic High”

or opened (pull up 100kΩ makes pin 19

6

“Logic High” automatically).

When pin 19 is “Logic Low” level, internal

frequency counter from 76kHz to 19kHz is

19

reset.

-

19kHz output (same phase as pilot tone).

When I2C bit “19K”=0, Pin 20 is kept

“Logic Low” level.
