The A9-CTC2 Test Fixture enables designers to access all signals from a DDR5 DIMM by plugging a DIMM directly into the test fixture. The test fixture is constructed from high speed, low loss MEGTRON 6 material. The test fixture also allows direct control of the I2C lines by connecting to a USB terminal. The test fixture can be assembled with a high performance Johnstech DDR5 DIMM socket, a standard DDR5 DIMM socket or the board can be assembled without any DDR5 DIMM socket attached.
