ESCRIPTION
The ICS840001 is a Fibre Channel Clock Generator
and a member of the HiPerClocks
TM
family of high
HiPerClockS™
performance devices from IDT. The ICS840001 uses
a 26.5625MHz cr ystal to synthesize either
106.25MHz or 212.5MHz, using the FREQ_SEL pin.
The ICS840001 has excellent phase jitter performance, over the
637kHz – 10MHz integration range. The ICS840001 is packaged
in a small 8-pin TSSOP, making it ideal for use in systems with
limited board space.

It is said that the LPC1114 board released in our forum is worth 39 US dollars~~
I first heard the news from gossip from my colleagues, hahaLPC1114 is worth $39. Wow, I didn’t expect such a small board to be so expensive!LPC1343 unknown~~~...

What good ideas do you have about odd-number division?
If it is the case, how would you make full use of FPGA resources to achieve odd frequency division?...
