CBTU0808

Dual lane PCI Express port multiplexer

Rev. 02 — 6 September 2007

Product data sheet

1. General description

The CBTU0808 is a dual lane port multiplexer designed to provide convenient and reliable

path switching for PCI Express signals. It is organized as two PCI Express lanes, each

consisting of a Transmit and Receive channel. Each channel has four ports, two (A and B)

on the source (or host) side and two (A and B) on the destination (or device) side. Each

port provides a pair of signal lines to support PCIe differential signaling.

Using specially designed high-bandwidth and high off-isolation switch elements, source

and destination ports can be connected or isolated in three possible conﬁgurations:

source A and B to destinations A and B respectively; or source A to destination B

(remaining ports isolated), or all ports isolated.

The switch elements are controlled by internal control logic to set switch positions in

accordance with these three conﬁgurations, selectable by CMOS inputs CTRL0 and

CTRL1 for lanes 0 and 1 respectively. Within a lane, the switch conﬁguration is always

applied identically to both transmit and receive channels.

The CBTU0808 is packaged in a 48-ball, depopulated 9 × 9 grid, 0.5 mm ball pitch, thin

proﬁle ﬁne-pitch ball grid array (TFBGA) package, which (while requiring a minimum

5 mm × 5 mm of board space) allows for adequate signal routing and escape using

conventional board technology.
