Notes:
1. The following reference designators were intentionally omitted: C15, C17, C21, C26, C27, C31–C33, R14, and R20.
2. Y2 class capacitors may also be used to achieve surge performance of 5 kV or better.
3. If JATE support is not required, R21, C12, and C23 may be removed and the following modifications implemented: R21 should be
replaced with a 0
resistor or shorted, and R4 should be changed to a 604 , 1/4 W, ±1%.
4. Alternate population option is C24, C25 (2200 pF, 3 kV, X7R, ±10% and C31, C32 not installed).
5. Install only if needed for improved radiated emissions performance (10 pF, 16 V, NPO, ±10%).
6. Y1, C34, and C35 should be installed if the Si3024 is configured as a primary device.
7. Several diode bridge configurations are acceptable (suppliers include General Semi., Diodes Inc.).
