PCA9615 - NXP

PCA9615 Plus differential I2C-bus buffer

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. It consists of two single-ended to differential driver channels for the SCL (serial clock) and.

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 condition before connection is made
• Compatible with I2C-bus Standard/Fast-mode and SMBus, Fast-mode Plus up to 1 MHz
• Single-ended I2C-bus o.
