PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The PLL’s two analog supplies, VCCA and VSSA, shall be filtered with two series ferrite beads and two shunt 0.1-µF and 0.01-µF capacitors. The ferrite on VSSA is preferred but optional.
COMPONENT | PARAMETER | RECOMMENDED VALUE | UNIT |
---|---|---|---|
Shunt Capacitor | Capacitance | 0.1 | µF |
Shunt Capacitor | Capacitance | 0.01 | µF |
Series Ferrite | Impedance at 10 MHz | >= 180 | Ω |
Impedance at 100 MHz | >= 600 | Ω | |
DC Resistance | < 0.40 | Ω |
Example ferrite bead recommendations are listed in Table 11-2.
PART NUMBER | R @ DC | Z @ 10 MHz | Z @ 100 MHz | Z @1-GHz SIZE |
