AFEs for Image Sensor

AKM's AFEs for the linear image sensor have wide product family.
Such as,
- the Timing Generator existence or not.
- CMOS or LVDS interface.
- for CIS sensor or CCD sensor.
- ADC input channels are 1CH to 6CH.

3-channel AFE with 10-bit 35MSPS/ch ADC and TG for CCD/CMOS linear sensor 

AK8464VN

The AK8464VN is 3-channel AFE for CCD/CMOS linear sensor. It integrates all peripheral circuits for linear sensor signal processing, such as timing generator (TG), crystal oscillator (OSC), synthesizer (SYNTH), spread-spectrum clock generator (SSCG) and so on. The AK8464VN can also operate up to 35MSPS/ch. Therefore, this product is ideal for all 3-channel scanner systems.

6-channel AFE with 10-bit 50MSPS/ch ADC and TG for Linear CCD

AK8446BVN

The AK8446B is 10-bit 10M ~ 50MSPS/ch analog front end IC for linear image sensor, which integrates six channels of CCD/CMOS sensor interface, 10-bit analog-to-digital converters, offset adjust DACs, programmable gain amplifiers, LVDS interface and timing generator for CCD control. AK8446 is suitable for high speed copier.

6-channel Linear Sensor
compatible 10-bit 40 MSPS x 3 Analog Pre-Processor

AK8448VQ

The AK8448 is analog front end IC for linear image sensor, which integrates six channels of CCD/CMOS sensor interface, three 10-bit 40MSPS analog-to digital converters, offset adjust DACs and programmable gain amplifiers. AK8448 is suitable for scanner applications.

3-channel LED Driver
with Charge Pump

AK7864AVN

The AK7864AVN is an IC with a built-in 3-channel LED driver for driving anode common R, G, B LEDs with constant current and a charge pump power supply for outputting anode voltage.
