LMK61E0M: Do we have more output channels version LMK61E0M like 1:4 or 1:8

Hi Tier

I found LMK61E0M which most suitable for customer need which is single-end output. programmable frequency. 100k-1Mhz output range.

But customer want to known do we have more output channels version? 

Thank you very much.

    Hi Tony, 

    Unfortunately LMK61E0M wouldn't be able to support output frequencies in the 100kHz-1MHz range. The VCO frequency goes down to 4.6 GHz and the maximum possible divider setting is a pre-divider of 5 and output divider of 256, for a total division of 1280. This gives a minimum output frequency of around 3.6 MHz 

    One option is to use LMK61E0M plus a buffer with programmable dividers like LMK01801 to achieve the fanout and frequencies they need.

    If the customer has some flexibility with their frequency plan or can implement a divider somewhere else in their system, we have LMK3H0102 which is fully programmable and supports up to 5 LVCMOS outputs down to 2.5 MHz. 

    Regards,
