General description
This 20-bit bus switch is designed for 2.3 V to 2.7 V VDD operation and SSTL_2 select
input levels.
Each host port pin is multiplexed to one of two DIMM port pins. When the SEL pin is HIGH
the A DIMM port is turned on and the B DIMM port is off. The ON-state connects the host
port to the DIMM port through a 20
nominal series resistance. When the port is off a
high-impedance state exists between the Host and disabled DIMM. The DIMM port is
terminated with a 100
resistor to ground. When the SEL pin is LOW the B DIMM port is
turned on and the A DIMM port is off.
The part incorporates a very low crosstalk design. It has a very low skew between outputs
(< 50 ps) and low skew (< 50 ps) for rising and falling edges. The part has optimal
performance in DDR data bus applications.
Each switch has been optimized for connection to 1-bank 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 CBTV4020 is characterized for operation from 0
°C to +85 °C.
