switch for PCI Express Gen2

Product data sheet
1. General description
CBTL02042A/B is a 2 differential channel, 2-to-1 multiplexer/demultiplexer switch for PCI
Express Generation 2 (Gen2), and other high-speed serial interface applications. The
CBTL02042A/B can switch two differential signals to one of two locations. Using a unique
design technique, NXP 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. CBTL02042A/B allows expansion of existing high speed ports
for extremely low power.
The device's pinouts are optimized to match different application layouts. CBTL02042A
has input and output pins on the opposite of the package, and is suitable for edge
connector(s) with different signal sources on the motherboard. CBTL02042B has outputs
on both sides of the package, and the device can be placed between two connectors to
multiplex differential signals from a controller. Please refer to Section 8 for layout
examples.

DHVQFN20 package die supply ground is connected to both GND pins and exposed center pad. GND pins
and the exposed center pad must be connected to supply ground for proper device operation. For
enhanced thermal, electrical, and board level performance, the exposed pad needs to be soldered to the
board using a corresponding thermal pad on the board and for proper heat conduction through the board,
thermal vias need to be incorporated in the printed-circuit board in the thermal pad region.
7. Functional description
Refer to Figure 1 “Functional diagram of CBTL02042A; CBTL02042B”.
7.1 Function selection and shutdown function
The CBTL02042A/B provides a shutdown function to minimize power consumption when
the application is not active, but power to the CBTL02042A/B is provided. The XSD pin
(active HIGH) places all channels in high-impedance state (non-conducting) while
reducing current consumption to near-zero. When XSD pin is LOW, the device operates
normally.

15. Soldering of SMD packages
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”.
15.1 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.
15.2 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 SnPb soldering
15.3 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

3.3 V, 2 differential channel, 2 : 1 MUX/deMUX switch for PCIe Gen2
15.4 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 9) than a SnPb 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 9 and 10

Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 9.
