CBTU0808
Dual lane PCI Express port multiplexer
Rev. 01 — 2 June 2006
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
14.1 Introduction to soldering surface mount packages
There is no soldering method that is ideal for all surface mount IC packages. Wave
soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch
SMDs. In these situations reflow soldering is recommended.
14.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and
binding agent) to be applied to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement. Driven by legislation and
environmental forces the worldwide use of lead-free solder pastes is increasing.
Several methods exist for reflowing; for example, convection or convection/infrared
heating in a conveyor type oven. Throughput times (preheating, soldering and cooling)
vary between 100 seconds and 200 seconds depending on heating method.
Typical reflow temperatures range from 215 °C to 260 °C depending on solder paste
material. The peak top-surface temperature of the packages should be kept below:

14.3 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices
(SMDs) or printed-circuit boards with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically
developed.
If wave soldering is used the following conditions must be observed for optimal results:
• Use a double-wave soldering method comprising a turbulent wave with high upward
pressure followed by a smooth laminar wave.
• For packages with leads on two sides and a pitch (e):

– larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be
parallel to the transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the
transport direction of the printed-circuit board.
The footprint must incorporate solder thieves at the downstream end.
• For packages with leads on four sides, the footprint must be placed at a 45° angle to
the transport direction of the printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement and before soldering, the package must be fixed with a droplet of
adhesive. The adhesive can be applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time of the leads in the wave ranges from 3 seconds to 4 seconds at 250 °C
or 265 °C, depending on solder material applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most
applications.
14.4 Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage
(24 V or less) soldering iron applied to the flat part of the lead. Contact time must be
limited to 10 seconds at up to 300 °C.
When using a dedicated tool, all other leads can be soldered in one operation within
2 seconds to 5 seconds between 270 °C and 320 °C.

For more detailed information on the BGA packages refer to the (LF)BGA Application Note (AN01026);
order a copy from your Philips Semiconductors sales office.

All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the
maximum temperature (with respect to time) and body size of the package, there is a risk that internal or
external package cracks may occur due to vaporization of the moisture in them (the so called popcorn
effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated Circuit
Packages; Section: Packing Methods.

These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no
account be processed through more than one soldering cycle or subjected to infrared reflow soldering with
peak temperature exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package
body peak temperature must be kept as low as possible.
[4]
These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the
solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink
on the top side, the solder might be deposited on the heatsink surface.
[5]
If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
[6]
Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
[7]
Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger
than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
[8]
Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered
pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by
using a hot bar soldering process. The appropriate soldering profile can be provided on request.
[9]
Hot bar soldering or manual soldering is suitable for PMFP packages.
