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.

7. Functional description
7.1 Functional description
7.1.1 General information
The CBTU0808 Dual lane PCI Express port multiplexer is designed to allow port switching
of up to two PCI Express lanes (each including a Transmit and Receive channel)
according to three switch configuration settings (described in Section 7.1.2.1). The basic
switch element of the CBTU0808 is designed integrally with its package and chip
interconnect to present an optimum characteristic on-impedance when used in a
PCI Express signaling environment, and to provide high off-port isolation and low
crosstalk.
7.1.2 Functional information
The following paragraphs describe the control and configuration possibilities available in
the CBTU0808.
7.1.2.1
Switch configuration
The position of the port switches is controlled by CMOS input signals CTRL[1:0] and can
be overridden by CMOS input TEST0 to disconnect (open) all ports between source and
destination. For a given lane, the switch positions are always identical between transmit
and receive channels. Lane 0 is controlled by CTRL0 and Lane 1 is controlled by CTRL1.
The truth table for the switch position as a function of these inputs is shown in Table 3.

14. Soldering
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
14.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
14.2 Wave and reflow soldering
Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
•
•
•
•
•
•
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus PbSn soldering
14.3 Wave soldering
Key characteristics in wave soldering are:
• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

14.4 Reflow soldering
Key characteristics in reflow soldering are:
• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 11) than a PbSn process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 8 and 9

times.

soldering, see Figure 11.
