PCA9514A规格书详情
General description
The PCA9513A and PCA9514A are hot swappable I2C-bus and SMBus buffers that allow I/O card insertion into a live backplane without corrupting the data and clock buses. Control circuitry prevents the backplane from being connected to the card until a stop command or bus idle occurs on the backplane without bus contention on the card. When the connection is made, the PCA9513A and PCA9514A provides bidirectional buffering, keeping the backplane and card capacitances isolated.
Rise time accelerator circuitry allows the use of weaker DC pull-up currents while still meeting rise time requirements. The PCA9513A and PCA9514A incorporates a digital ENABLE input pin, which enables the device when asserted HIGH and forces the device into a Low current mode when asserted LOW, and an open-drain READY output pin, which indicates that the backplane and card sides are connected together (HIGH) or not (LOW).
Features
■ Bidirectional buffer for SDA and SCL lines increases fanout and prevents SDA and SCL corruption during live board insertion and removal from multi-point backplane systems
■ Compatible with I2C-bus Standard mode, I2C-bus Fast mode, and SMBus standards
■ Built-in ∆V/∆t rise time accelerators on all SDA and SCL lines (0.8 V threshold)
■ Rise time accelerator threshold moved from 0.6 V to 0.8 V for improved noise margin
■ Active HIGH ENABLE input
■ Active HIGH READY open-drain output
■ High-impedance SDAn and SCLn pins for VCC = 0 V
■ 92 µA current source on SCLIN and SDAIN for PICMG backplane applications (PCA9513A only)
■ Supports clock stretching and multiple master arbitration and synchronization
■ Operating power supply voltage range: 2.7 V to 5.5 V
■ I/Os are not 5.5 V tolerant
■ 0 Hz to 400 kHz clock frequency
■ ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
■ Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
■ Packages offered: SO8, TSSOP8 (MSOP8)
Applications
■ cPCI, VME, AdvancedTCA cards and other multipoint backplane cards that are required to be inserted or removed from an operating system
