SR1913 is the smallest size 3.6mm x7mm BGA video encoder with frame rate buffer.
It is an advanced hardware-based image processor designed to provide programmable wide angle lens distortion compensation and keystone compensation.
This device accepts digital video input ports for 10-bit interlaced or progressives.
Output for digital and analog CVBS video output with 10-bit progressive or interlace scan video with frame rate conversion.

Advanced frame rate control technology
Whatever CMOS sensor output is, SR1913 will smoothly convert progressive signal to CVBS. You can configure your CMOS sensor that is at low frame rate in low lux environment At low lux environment, the exposure will rise
Mega pixel YUV 422 Progressive input source and CVBS output
The video source is more than VGA. It will have enough video information to do the ePTZ and Keystone. ePTZ:
Keystone:
Case 1: AUTO BOOT ( TO save your eBOM and PCB dimension)
This is simple mode that is digital CMOS to CVBS without any special function
Case 2: MCU Mode If you need fisheye correction, keystone, ePTZ.......
Case 3: MCU + AUTO BOOT If you want to powerful function and need extra control.....
