11.2.2 Recommended DLPC350 MOSC Crystal Oscillator Configuration

The DLPC350 controller requires an external reference clock to feed its internal PLL. This reference may be supplied via a crystal or oscillator. The DLPC350 controller accepts a reference clock of 32 MHz with a maximum frequency variation of 100 ppm (including aging, temperature, and trim component variation). When a crystal is used, several discrete components are also required, as shown in Figure 26.

CL = crystal load capacitance in F
CL1 = 2 × (CL – Cstray-MOSC)
CL2 = 2 × (CL – Cstray-MOSCN
Cstray-MOSC = sum of package and PCB capacitance at the crystal pin associated withe ASIC signal MOSC
Cstray-MOSCN = sum of package and PCB capacitance at the crystal pin associated withe ASIC signal MOSCN

PCB layout A ground isolation ring around the crystal

If an external oscillator is used, then the oscillator output must drive the MOSC pin on the DLPC350 controller, and the MOSCN pin should be left unconnected. Note that the DLPC350 controller can only accept a triangular waveform.

Similar to the crystal option, the oscillator input frequency is limited to 32 MHz.

It is assumed that the external crystal or oscillator stabilizes within 50 ms after stable power is applied.
