The utility model relates to filter protection circuit and camera of camera head, including
image acquisition sensor, connecting port and
image processing chip, still including TF common mode filter circuit, electrostatic protection circuit and
spread spectrum IC circuit, TF common mode filter circuit is connected with
image acquisition sensor, electrostatic protection circuit and TF common mode filter circuit and connecting port are connected, and the CSI the CLK port of
image processing chip, the MCLK port of connecting port all are connected with
spread spectrum IC circuit, application circuit of this application can reduce the
common mode noise of data to the greatest extent, reduce EMI
radiation, can reduce electrostatic interference
data transmission, can also make the synchronous
clock of protocol also have
spread spectrum, thereby reducing
clock radiation, this application can solve the EMI
radiation emission and electrostatic protection problem of MIPI CSI -2 camera head very well, especially applicable to small, data bandwidth is high,
clock frequency is high and the camera product of transmission MIPI CSI -2 protocol.
