PRODUCTION DATA.
PARAMETER | NOMINAL | UNIT |
---|---|---|
PLL_REFCLK_I TO GND capacitance | 1.5 | pF |
PLL_REFCLK_O TO GND capacitance | 1.5 | pF |
PARAMETER | RECOMMENDED | UNIT |
---|---|---|
Crystal circuit configuration | Parallel resonant | |
Crystal type | Fundamental (first harmonic) | |
Crystal nominal frequency | 24 or 16 | MHz |
Crystal frequency tolerance (including accuracy, temperature, aging and trim sensitivity) | ±200 | PPM |
Maximum startup time | 1.0 | ms |
Crystal equivalent series resistance (ESR) | 120 max | Ω |
Crystal load | 6 | pF |
RS drive resistor (nominal) | 100 | Ω |
RFB feedback resistor (nominal) | 1Meg | Ω |
CL1 external crystal load capacitor | See equation in Figure 18 notes | pF |
CL2 external crystal load capacitor | See equation in Figure 18 notes | pF |
PCB layout | A ground isolation ring around the crystal is recommended |
If an external oscillator is used, then the oscillator output must drive the PLL_REFCLK_I pin on the DLPC150 DLPC150 controller and the PLL_REFCLK_O pins should be left unconnected.
