Description
The LTC4300A-1CMS8#TRPBF is a signal buffer, repeater, splitter that allows for I/O card insertion into a live backplane without data and clock bus corruption. This 2-wire bus buffer provides bidirectional buffering, which keeps backplane and card capacitances isolated. It has low offset and high VOL tolerance, which allows cascading of multiple devices on the clock and data busses. The device can generate up to 16 clock pulses and a stop bit in an attempt to free the bus if the bus is stuck and DISCEN is high. This device is used in various applications, such as live board insertion, servers, capacitance buffer, bus extender, RAID systems, and ATCA.
Specifications and features
The LTC4300A-1CMS8#TRPBF has the following specifications and features:
- Bidirectional buffer increases fanout
- 60mV buffer offset independent of load
- Optional disconnect when bus is stuck low
- Prevents SDA and SCL corruption during live board insertion and removal from backplane
- Level shift 2.5V, 3.3V and 5V busses
- Compatible with non-compliant VOL I2C devices
- Isolates input SDA and SCL lines from output
- Compatible with I2C™, I2C Fast-Mode and SMBus
- READY open drain output
- FAULT open drain output
- 1V precharge on all SDA and SCL lines
- Optional rise time accelerators
- High impedance SDA, SCL pins for VCC = 0
- Available in small 12-pin DFN (4mm x 3mm) and 16-lead SSOP packages
Application Scenarios
The LTC4300A-1CMS8#TRPBF is commonly used for live board insertion, servers, capacitance buffer, bus extender, RAID systems, and ATCA.
Comparison
Advantages- Allows for I/O card insertion into a live backplane without corruption of the data and clock busses
- Bidirectional buffering keeps the backplane and card capacitances isolated
- Low offset and high VOL tolerance allows cascading of multiple devices on the clock and data busses
