Description
The PCA9615 is a Fast-mode Plus (Fm+) SMBus/I2C-bus buffer that extends the normal single-ended SMBus/I2C-bus through electrically noisy environments using a differential SMBus/I2C-bus (dI2C) physical layer, which is transparent to the SMBus/I2C-bus protocol layer.
Features
- New dI2C-bus buffers offer improved resistance to system noise and ground offset up to 1⁄2 of supply voltage.
- 2 channel dI2C (differential I2C-bus) to Fm+ single-ended buffer operating up to 1 MHz with 30 mA SDA/SCL drive capability.
- Hot swap (allows insertion or removal of modules or card without disruption to bus data).
- EN signal (PCA9615 input) controls PCA9615 hot swap sequence.
- Bus idle detect (PCA9615 internal function) waits for a bus idle con.
