CBTW28DD14
14-bit bus switch/multiplexer for DDR2-DDR3 applications
7.
Functional description
Refer to Figure 1 “Functional diagram”.
The CBTW28DD14 uses a 1.5 V or 1.8 V power supply. All signal paths are implemented
using high-bandwidth pass-gate technology and are non-directional. No clock or reset
signal is needed for the multiplexer to function. The switch position for the channels is
selected using the select signal SEL. The detailed operation is described in Section 7.1.
7.1 Function selection
The internal multiplexer switch position is controlled by two logic inputs, SEL and EN, as
described in Table 3.
