The external clock source in this … WebYou drive the OSC_CLK_1 pin at an incorrect frequency. Select one of the following input reference clock frequencies to drive the OSC_CLK_1 pin: 25 MHz. 100 MHz. 125 MHz. The Intel® Agilex™ device multiplies the OSC_CLK_1 source clock frequency to generate a 250 MHz clock for configuration.

WebRTC can be operated in different modes. The module has a maximum clock frequency of 160 MHz that means the computing power up to 600 DMPIS.
