CBTL04083BBS

CBTL04083A / B为4个差分通道， 2对1多路复用器/多路分解器开关用于PCI Express第3代（第3代）的应用程序。 CBTL04083A/B is a 4 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI Express Generation 3 Gen3 applications.

Overview

CBTL04083A/B is a 4 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI Express Generation 3 Gen3 applications. The CBTL04083A/B can switch four differential signals to one of two locations. Using a unique design technique, has minimized the impedance of the switch such that the attenuation observed through the switch is negligible, and also minimized the channel-to-channel skew as well as channel-to-channel crosstalk, as required by the high-speed serial interface. CBTL04083A/B allows expansion of existing high speed ports for extremely low power.

The device"s pin out are optimized to match different application layouts. CBTL04083A has input and output pins on the opposite of the package, and is suitable for edge connectors with different signal sources on the motherboard. CBTL04083B has outputs on both sides of the package, and the device can be placed between two connectors to multiplex differential signals from a controller.
