1. VLN1, VLP, VOFF, VREF, VREF1, VLN2, and VREF2 are generated on-chip, but user may disable internal bias (via two-
2. All bias pins should be decoupled with 0.1µF ceramic and 10µF electrolytic capacitors. (Please see board connections.)
3. Digital outputs can drive standard CMOS circuits with 30pF load, but less load capacitance results in less substrate

not be disabled. VRST_PIX and VRSTLOW are not generated internally and external voltages must be applied.
Capacitors should be placed as physically close as possible to the MT9V403 package.
