SN74LVC1GX04: XTAL buffer

Hyeonyeop Cho
Prodigy 10 points
Part Number: SN74LVC1GX04

Hello~.

I need to pass the clock to two ICs with one XTAL.

So, I found the SN74LVC1GX04 like below.

 

Vcc = 3.3V

XTAL Frequency : 25MHz

I can confirm that the gain of the amplifier of SN74LVC1GX04 is reduced at 25MHz.

In this case, Can 25MHz output be guaranteed normally?

Thank you 

Best regards.

    In theory, any gain above 0 dB is OK. So with 20 dB at 25 MHz, I expect it to work.

    In practice, the oscillator circuit is an analog circuit and depends on the characteristic of all components. Test with the real circuit; see section 9.2.1 of the datasheet for possible modifications.
