age to become 1.8V or 3.3V, depending on the placement of the shorting jumper on J6. A similar configuration is
supported for U11 side 2.
MachXO2 I/O Bank Voltages
Most of the bank voltages on the MachXO2 device (U8) have been hard-wired to selectable power supply values.
Banks 0, 2 and 5 are normally 2.5V, but they can be modified by the location of J6. These banks interface to the
parallel ISP bus and the sensor configuration pins. Banks 1, 3 and 4 are normally 1.8V, but they can be modified by
the location of J20. These I/Os interface to the low power SDRAM memory, as shown in Table 2.
Table 2. MachXO2 (U8) Bank Voltage Settings
Crystal Oscillators
There is one crystal oscillator and one MEMS-based oscillator on the MachXO2 Dual Sensor Interface Board
(Table 3). The crystal oscillator is used for the USB port connection. The MEMS-based oscillator is 27 MHz and is
delivered to the MachXO2 device as a design reference clock to provide a clock to the sensors, if desired.

Image Sensor Connectors
The board has six Hirose connectors, configured as three pairs. These are located at J1 and J5, J4 and J11, and
J7 and J8. The J1 and J5 pair are for sensor #1. The J4 and J11 pair are for sensor #2. The J7 and J8 pair allow
the DSIB to plug into the HDR-60 Base Board.
HiSPi Connector for Sensor #1 (J1)
Bank 2 of the MachXO2 device can receive HiSPi sub-LVDS video signals from connector J1. This connector can
also receive serial signals from the Panasonic MN34041. When receiving serial signals, set the MachXO2 input
type to LVDS with differential 100 ohm termination. The signal connections between the MachXO2 device and the
HiSPi connector are shown in Table 4.
