Evaluation Board Overview
The evaluation boards are designed to demonstrate the features of
image sensors products from ON Semiconductor. This headboard is
intended to plug directly into the Demo 3 system. Test points and
jumpers on the board provide access to the clock, I/Os, and other
miscellaneous signals.
Features
•Clock Input
♦Default – 27 MHz Crystal Oscillator
♦Optional Demo 3 Controlled MClk
•Two-wire Serial Interface
♦Selectable Base Address
•Parallel Interface
•ROHS Compliant

Jumper Pin Locations
The jumpers on headboards start with Pin 1 on the
leftmost side of the pin. Grouped jumpers increase in pin
size with each jumper added.

Interfacing to ON Semiconductor Demo 3 Baseboard
The ON Semiconductor Demo 3 baseboard has a similar
52-pin connector which mates with J2 of the headboard.
The four mounting holes secure the baseboard and the
headboard with spacers and screws.
Shorted Jumpers for Power Measurement
Different supplies to the evaluation board are provided by
trace shorted jumper, for any voltage and power
measurements. To conduct current for current measurement
on a given power rail, cut the trace between the two pins of
their respective JP, and insert an ammeter prior to powering
up the system. The figure below shows where the trace to cut
is located.
