Forum: Oscillators |
In my design of an application where I need to communicate with the outside world thro' serial interface - I have to use a 16-Bit Microcontroller. I want to keep cost of my design low - Shall I use an internal oscillator or go by external resonator?
Will it be possible for you to provide me the specific part number of Silicon Labs microcontroller with internal oscillator ?
Thank You
Hi Bruce,
Depending on the required clock frequency
Consider the tradeoffs:
---ROHS?
--ppm over temp
--board space
--estimated annual usage
From my own experience, external resonators are far more cost effective, provided you source the part from a tier 1 supplier, pick the right package and load capacitors (i.e. 0402 or smaller case size + trace length capacitance...)
