1.1 Sensor overview
The VV6501 VGA image sensor produces raw digital video data at up to 30 frames per second. The
image data is digitised using an internal 10-bit column ADC. The resulting 10-bit output data
includes embedded codes for synchronization. The data is formatted as 5-bit nibbles. A separate
data qualification clock (qck) and frame start (fst) signals are also provided.
The sensor is fully configurable using an I²C interface.
The sensor also contains an audio low-noise preamplifier for use with an external microphone.
The sensor is optimized for USB applications and contains voltage regulators which drive external
pass transistors to produce 3V3 and 1V8 supplies. These supplies may be used by external
processors. A dedicated SUSPEND input pin may be used to force the device into a low power state
while maintaining the device configuration. A power-on reset signal (PORB) may be used to reset
external devices.
