7 Standard Device Configuration Examples
7.0 Oscillator Configurations
Figure 7.1 3-Pins Ceramic Resonator Configuration
Figure 7.1 illustrates how to use the FT2232D with a 3-Pin Ceramic Resonator. A suitable part would be a
ceramic resonator from Muratas CERALOCK range. (Murata Part Number CSTCR6M00G15), or equivalent.
3-Pin ceramic resonators have the load capacitors built into the resonator so no external loading
capacitors are required. This makes for an economical configuration. The accuracy of this Murata ceramic
resonator is +/- 0.25% and it is specifically designed for USB full speed applications. A 1 MegaOhm
loading resistor across XTIN and XTOUT is recommended in order to guarantee this level of accuracy.
Other ceramic resonators with a lesser degree of accuracy (typically +/- 0.5%) are technically out-with
the USB specification, but it has been calculated that using such a device will work satisfactorily in
practice with a FT2232D design. An example of such a device is Muratas CSTLSM00G53.
