CBTV24DD12A
12-bit bus switch/multiplexer for DDR4-DDR3-DDR2
applications
Rev. 2 — 15 November 2017
Product data sheet
1. General description
CBTV24DD12A is designed for 1.8 V/2.5 V/3.3 V supply voltage operation and it supports
Pseudo Open Drain (POD), SSTL_12, SSTL_15 or SSTL_18 signaling and CMOS select
input levels. This device is designed for operation in DDR4, DDR3 or DDR2 memory bus
systems, with speeds up to 3200 MT/s.
The CBTV24DD12A has a 1 : 2 switch or 2 : 1 multiplex topology and offers a 12-bit wide
bus. Each 12-bit wide A-port can be switched to one of two ports B and C, for all bits
simultaneously. Each port is non-directional due to the use of FET switches, allowing a
multitude of applications requiring high-bandwidth switching or multiplexing.
The selection of the port is by a simple CMOS input (SELect). Another CMOS input
(ENable) is available to allow all ports to be disconnected. The SEL0, SEL1 and EN input
signals are designed to operate transparently as CMOS input level signals up to 3.3 V.
CBTV24DD12A uses NXP’s proprietary high-speed switch architecture providing high
bandwidth, very little insertion loss, return loss, and very low propagation delay, allowing
use in many applications requiring switching or multiplexing of high-speed signals. It is
available in a 3.0 mm 8.0 mm TFBGA48 package with 0.65 mm ball pitch, for optimal
size versus board layout density considerations. It is characterized for operation from
10 C to +85 C.
