DESCRIPTION
This 10-bit bus switch is designed for 2.3 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 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 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 × 7 pF) allows
data transfer to be made with minimal propagation delay.
The CBTV4010 is characterized for operation from 0 to +85 °C.
