The Renesas Electronics second generation 2-input/12-output differential mux used for Intel purley and newer platforms. It utilizes Low-Power HCSL-compatible outputs to reduce power consumption and termination resistors. 2 configurable low drift I2O delays up to 2.9ns, maintain transport delay for various topologies
LP-HCSL outputs with Zout = 85Ω eliminate 48 resistors
9 selectable SMBus addresses multiple devices can share same SMBus segment
Separate VDDIO for outputs allows maximum power savings
