I/O

Function

I Data input. There is no built-in amplifier on this pin.

O EIAJ data through output

Validity flag output

O Alternatively, the microprocessor interface can set this pin to output the EIAJ input data unchanged.

RC oscillator input

I

This circuit generates a clock used to detect incorrect PLL locking and to reset the PLL system.

RC oscillator output

O This pin outputs a clock with a frequency of about 40 kHz when the component values specified in the sample

application circuit are used.

I CLKOUT2 output clock switching: Low = 256 fs, high = 128 fs

I Clock mode switching: Low = 384 fs, high = 512 fs

I

Test pin (Should be tied low in normal operation.)

I

I Used to start system operation after power is applied.
