STV0984
2 Megapixel SMIA profile 2 mobile imaging processor
Data Brief
Features
■ Supports 2 SMIA profile 2^(a) compliant sensors
mutually exclusive up to 2 Megapixel
(1600x1200) resolution
■ Enhanced video processor
– Noise/defect filtering, color reconstruction,
sharpness enhancement and radial
corrections
– Statistic processor for exposure and white
balance and autofocus control
– GPIOs and ADC to control external
actuators
■ 2 video pipes for full frame rate concurrent
viewfinder and video/still capture. Single shot
(e.g. flashgun) thumbnail generation
– Gamma correction programmable for both
CRT and LCD displays. Color correction
matrix
– Digital zoom: smooth downscale capability
(independent X/Y characteristics) and up-
scale capability to 4x
■ SMIA output formats: JPEG, YUV4:2:2,
YUV420, RGB888, RGB565, RGB444
■ 4:2:0 JPEG compression with programmable
quantization matrix and target file size
■ JPEG operations up to 30 fps
■ Interleaved video modes (concurrent still/video
+ ViewFinder)
– ‘Alternate CCP frame’ mode up to 15 fps
– ‘Single CCP frame’ mode up to 30 fps
■ CCP transmitter derating capabilities
(by 2,3,4,5 and 6) of sensor high speed clock
■ Interfaces
– Sensor interface: 2x CCP2.0^(b) serial
receivers (csi class 2 receivers)

Description
The STV0984 is a new generation, ultra low
power Megapixel digital image processor
designed to fit into mobile applications. STV0984
comes with support for 2 SMIA sensor heads and
programmable intelligent General Purpose IOs
engine to control, through dedicated firmware,
external actuators such as flashgun, white led and
autofocus solution. STV0984 provides internal
buffering capability along with a versatile clock
manager to accommodate different data rates
between input sensors and host interface.
