4.2 Clocks
The clock for the S1D13719 Mobile Graphics Engine is provided by a 32.768kHz oscillator.
The S5U13719P00C100 evaluation board has a DIP14 footprint for an optional second oscillator, Y2. This is
provided for cases requiring a different clock frequency for the S1D13719 Mobile Graphics Engine. To use Y2, an
oscillator must be populated in the Y2 footprint and the following board modifications must be made.
1. Remove R20 (33 ohm resistor, size 0402) to cut the output of Y1.
2. Populate R23 with a 33 ohm resistor, size 0402, to connect the output of Y2 to the CLKI input of the
S1D13719 Mobile Graphics Engine.
4.3 Reset
The S5U13719P00C100 evaluation board can be reset using a push-button, or via an active low reset signal from
the host development platform, on pin 30 of connector H1.
The reset signal will reset the S1D13719 Mobile Graphics Engine and is also available on the H3 and H7 connectors,
so that camera modules connected to the board can be reset.
4.4 Host Interface
4.4.1 Direct Host Bus Interface Support
All S1D13719 host interface pins are available on connector H1 and H2 which allows the S5U13719P00C100 evalu-
ation board to be connected to a variety of development platforms. For detailed S1D13719 pin mapping, refer to the
S1D13719 Hardware Functional Specification
, document number X59A-A-001-xx.
The following figure shows the location of host bus connector H1 and H2. H1 and H2 are 0.1x0.1”, 34-pin headers
(17x2).
