11.1.2 DLPC3478 Reference Clock

The DLPC3478 requires an external reference clock to feed its internal PLL. A crystal or oscillator can supply this reference. For flexibility, the DLPC3478 accepts either of two reference clock frequencies (see Table 13), but both must have a maximum frequency variation of ±200 ppm (including aging, temperature, and trim component variation). When a crystal is used, several discrete components are also required as shown in Figure 37.

A. CL = Crystal load capacitance (farads)
B. CL1 = 2 × (CL – Cstray_pll_refclk_i)
C. CL2 = 2 × (CL – Cstray_pll_refclk_o)
D. Where: Cstray_pll_refclk_i = Sum of package and PCB stray capacitance at the crystal pin associated with the ASIC pin pll_refclk_i. Cstray_pll_refclk_o = Sum of package and PCB stray capacitance at the crystal pin associated with the ASIC pin pll_refclk_o.
