MCZ33781EKR2

MCZ33781EKR2 is a quad DSI 2.02 host device with differential drive and frequency spreading. 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 server devices. The differential mode of the 33781 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 frequencies, reducing the energy in any single frequency.

• Dual SPI interface, enhanced bus fault performance
• Automatic message cyclical redundancy checking (CRC) generation and checking for each channel
• 8- to 16bit messages with 0- to 8bit CRC, independent frequency spreading for each channel
• Pseudo bus switch feature on channel 0
• Supply voltage range from 3.0 to 5.25V
• IVSUPT supply current (test mode, CLK = 4.0MHz) is 33mA max (signal, idle (Ibus = 0), TA = 25°C)
• Input capacitance is 10pF max (CSn, MOSI0, and SCLKn, TA = 25°C)
• Signal mode over-current shutdown range from 20 to 60mA (l ISSD l DnH, DnL, TA = 25°C)
• 32 SOICW EP package
• Temperature range from -40°C to 90°C
