Connect an OEM-IMU-ADIS-16488 Directly to an OEM7 Receiver Card

The OEM-IMU-ADIS-16488 can connect directly to SPI capable OEM7 receivers, such as the OEM7600, OEM7700 and OEM7720, using a SPI connection. The SPI connection handles timing and data communication between the receiver and IMU.

The interface to the OEM-IMU-ADIS-16488 must provide:

• a Samtec CLM-112-02 connector

  This connector mates with the connector on the OEM-IMU-ADIS-16488. See Figure: OEM-IMU-ADIS-16488 Pin Locations for the location of the IMU connector and pins.

• a SPI port connection to the OEM7 receiver

  Refer to the following table for the connections required between the IMU and receiver. For information about the receiver connector, see OEM7600 Interface Connector, OEM7700 Interface Connector or OEM7720 Interface Connector.

• a 3.3 VDC (±0.3 VDC) regulated power supply

  Refer to the following table for the location of the power supply connections.

Receiver to OEM-IMU-ADIS-16488 Pin Connections

ADIS‑16488		Receiver
Pin	Pin Name	Pin	Pin Name	Description
3	SCLK	44	SPI_SCLK	SPI Serial Clock
4	SDO	43	SPI_MISO	SPI Data Output
5	SDI	41	SPI_MOSI	SPI Data Input
6	CS	42	SPI_nCS	SPI Chip Select
7	DIO1	26	EVENT_OUT2	Synchronization signal
8	RST	–	–	Reset IMU RST must be high for the IMU to be active. To enable the IMU when the receiver is powered on, connect this pin to Pin 1 or Pin 2 of the receiver interface connector through a 10 kΩ resistor (recommended). Can also connect this pin to any stable 3.3 VDC power supply or output configuration to have more control over when IMU is enabled. When using this configuration note that: pin 8 must be pulled low for greater than 100 ms to properly soft-reset the IMU pin has an internal pull-up resistor
9	DIO2	29	EVENT_IN2	Data ready
10-12	VDD	–	–	3.3 VDC power supply
13-15	GND	–	–	Digital ground

In the table above, the receiver pin numbers are for OEM7600, OEM7700 and OEM7720 receivers. For the location of the receiver card pins, refer to Technical Specifications.
