[lpc2000] 100 MHz clock using LPC2138

2005-06-12 by sudip nag

My requirement is basically to transmit data from one microcontroller (LPC2138) to the other at 100MHz. Thus the clock generated must synchronize the data. Si4112 has IF out relying upon its separate crystal. This may cause data transition mismatch with driving clock. So its preferable to generate clock from LPC2138. Please suggest any outcome.

such high frequency.

The Si4112 (derivative of Si4133) from www.silabs.com has an output 
from 62 MHz to 1 GHz (and the part will work lower). They are 
available from Digikey.
