AK8464 3ch input 10bit 35MSPS/ch AFE for MFP or CIS module with CCDI/F, TG, LVDS, LDO, Synth_PLL, and SSCG_PLL 1.General Description
The AK8464 is a 3-channel 10bit 35MSPS/Ch A/D convertor integrating TG, LVDS, LDO, Synth_PLL, SSCG_PLL and OSC circuits. The Timing Generator(TG) can generate CCD sensor driving pulse for linear CCD, CIS sensor driving pulse for CIS modules and LED control pulse. It is suitable for MFPs and CIS modules.
