Other Parts Discussed in Thread: LMK04906

Hi ,

Our customer has a question about the frequency multiplying of LMK04906 device.

They want to make from the input frequency '19.42857143.....MHz' to the output frequency '155.4286MHz'.

The rate of multiplication is 8.

LMK04906 device can provide the frequency (155.4286MHz) ?

Also, the input frequency '19.42857143...MHz' is programmable by 122.88MHz multiplideb by 1275 and divided by 8064.

Best Regards,

Kato / Japan disty
