3 V to 2.
7 V VCC operation and SSTL_2 select input levels.
Each Host port pin is multiplexed to one of four DIMM port pins.
When the S pin is low the corresponding 10-bit bus switch is turned on.
The on-state connects the Host port to the DIMM port through a 20 Ω nominal series resistance.
When the S pin is high the switch is open and a high-impedance state exists between the two ports.
The DIMM port is terminated with a 100 Ω resistor to ground when the S pin is high.
The design is intended to have only one DIMM port active at any time.
The part incorporates a very low cross-talk design.
It has a very low skew between outputs (< 50 ps) and low skew (< 50 ps) for rising and falling edges.
The part has optional performance in DDR data bus applications.
Each switch has been optimized for connection to 1 or 2-bank DIMMs.
The low internal RC time constant of the switch (20 Ω × 7 pF) allows data transfer to be made with minimal propagation delay.
The CBTV4010 is characterized for operation from 0 to +85 °C.
