MAX6618AUB+

MAX6618AUB+ is a PECI-to-I²C translator. It provides an efficient, low-cost solution for PECI(1.0)-to-SMBus/I²C protocol conversion. The PECI(1.0)-compliant host reads temperature data directly from up to four PECI(1.0)-enabled CPUs. This translator will only communicate with CPUs that support PECI 1.0. The I²C interface provides an independent serial communication channel to communicate synchronously with peripheral devices in a multiple hosts or multiple server system. This interface allows a maximum serial data rate of 400Kbps. It is used in applications such as servers, workstations, desktop computers.

• 400Kbps I²C-compatible, 2-wire serial interface
• Supply voltage range from +3V to +3.6V, programmable temperature offsets
• PECI(1.0)-compliant port, PECI(1.0)-to-I²C translation
• VREF input refers logic levels to the PECI supply voltage
• Automatic I²C bus lockup timeout reset, supply current is 4mA typ at (SCL = 400KHz)
• Serial-clock frequency is 400KHz maximum at (VCC = +3V to +3.6V)
• Bit time jitter is 1% typical at (VCC = +3V to +3.6V, VREF = +0.95V to +1.26V)
• Input capacitance is 10pF typical at (VCC = +3V to +3.6V, VREF = +0.95V to +1.26V)
• Operating temperature range from -20°C to +120°C
• 10µMAX package
