  • Page 16: Functional Description

    4.2.1 ONTROLLER NFORMATION In this section RTD provides information about the NXP PCA9616 buffer that is used on the DM35MRM128HR to provide the differential I C bus. If you do not use the CM35I2C03HR as a host I C host, the information below can be used to develop a differential I C interface for your host module.

  • Page 17: Nxp Pca9616 Buffer

    C interface is designed for 100Ω impedance transmission lines. Using the termination circuit shown above, RTD suggest using CAT5, CAT6, or CAT7 data cable for cabling between host and slave. CAT5, CAT6 and CAT7 provide 4 twisted pairs, the 4 pairs can be used for 3 signals (INT, CLK, DATA) and power.

  • Page 18: Switch Matrix

    Switch Matrix The DM35MRM128HR is a high-density matrix module consisting of 8 rows by 16 columns of type A reed relays. This configuration allows for 128 crosspoints. This allows for users to programmatically switch wiring configuration as needed, this makes for a perfect tool for DUT (device under test) testing.
