CCS Technical Documentation Camera Module 0.01 uF. Extclk has 4 operating modes depending on the wireless system in which the camera module is used. The Extclk is active before VDD is on. This Extclk shall be exclusively used for generating any other clocks DC characteristics (1) Maximum ratings VDD 3.6 V VDDI 2.7 V Input signals, min -0.3 V Input signals, max VDDI (1.8V) + 0.3 V Note: Values respect to GND. (2) DC characteristics of each signal are shown in the table below.
Camera Module CCS Technical Documentation Signals specifications Signals and timing The fast serial interface of digital image data is employed for the VGA camera module. The fast serial interface described in this document is named CCP (Compact Camera Port). In terms of signaling scheme, CCP is based on the idea of IEEE standard LVDS signaling scheme (current mode differential low voltage signaling method). CCP described in this document utilizes lower voltage than that of standard LVDS.
