Architecture

Aptina Confidential and Proprietary

Preliminary

Crystal Usage

As an alternative to using an external oscillator, a fundamental 27 MHz crystal may be

connected between EXTCLK and XTAL. Two small loading capacitors of 10–22 pF of NPO

dielectric should be added as shown in Figure 3.

Aptina does not recommend using the crystal option for applications above 85°C. A

crystal oscillator with temperature compensation is recommended.

Using a Crystal Instead of an External Oscillator

Note:

Value of load cap is Xtal dependent. Xtal with small load cap is recommended.
