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. > > > LPC2138 may have a clock lower then 60MHz so it is not possible to generate directly from LPC2138 100MHz clock. Also if you need to transfer data from a LPC2138 to a different mcu you may not do it at 100MHz. I think that also using assembler you may transmit to a fraction of 60MHz may be burst data at 10MHz if your mcu hasn't to do anything else. >Sudip > >weverest3 <weverest@...> wrote: >--- In lpc2000@yahoogroups.com, sudip nag <sudipnag1@y...> wrote: > > >>I would like to generate 60 MHz to 100 MHz clock, in controlled step >> >> >of 1 MHz, with 50% duty cycle using LPC2138.
