CBTV4010
FEATURES
DESCRIPTION
• Enable signal is SSTL_2 compatible
• Optimized for use in Double Data Rate (DDR) SDRAM
applications
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 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.
• Designed to be used with 400 Mbps/200 MHz DDR data bus
• Switch on resistance is designed to eliminate the need for series
resistor to DDR SDRAM
• 20 Ω on resistance
• Internal 100 Ω pull-down resistors
• Low differential skew
• Matched rise/fall slew rate
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.
• Low cross-talk data-data/data-DQM
• Independent DIMM control lines
• Latch-up protection exceeds 500 mA per JESD78
• ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
3. The package thermal impedance is calculated in accordance with JESD 51.
