Advantages and Disadvantages

Advantages

The 33780 is a master device for two differential DBUS buses. It contains the logic to interface the buses to a standard serial peripheral interface (SPI) port and the analog circuitry to drive data and power over the bus as well as receive data from the remote slave devices.

The differential mode of the 33780 generates lower electromagnetic interference (EMI) in situations where data rates and wiring make this a problem. Frequency spreading further reduces interference by spreading the energy across many channels, reducing the energy in any single channel.

Product Functions

The 33780 is intended to be used as a master device in a distributed system. It contains both protocol generators and physical interfaces to allow an MCU to communicate with devices on the bus using only a simple SPI interface. Two differential busses are provided.

Using a loop-back wire allows operation of the bus in the presence of an open circuit. This is immediate and no interruption is caused by the open circuit. The differential outputs have reduced electromagnetic radiation and susceptibility.

The equivalent bus capacitance consists of capacitors connected between the two bus wires and capacitors between the bus wires and ground. Because the voltage change on either of the bus wires to ground is only 1/2 the amount of change between the two bus wires, the capacitance to ground only conducts half as much current as it would if connected directly across the bus. The equivalent bus capacitance of a capacitor to ground from the bus wires is one half of the actual amount of the capacitor. The amount of capacitance from either bus wire to ground should be kept the same in order to achieve the lowest radiated EMI energy.

The 4.7 nF capacitors required between the bus wires and ground result in an equivalent of 2.35 nF of capacitance across the bus as seen by either bus wire.

Product Manufacturer

NXP Semiconductors N.V. is a Dutch global semiconductor manufacturer headquartered in Eindhoven, Netherlands. The company employs approximately 31,000 people in more than 35 countries, including 11,200 engineers in 33 countries. NXP reported revenue of $6.1 billion in 2015, including one month of revenue contribution from recently merged Freescale Semiconductor.

On October 27, 2016, it was announced that Qualcomm would try to buy NXP, but because the Chinese merger authority did not approve the acquisition before the deadline set by Qualcomm, it was effectively canceled on 26 July 2018.
