CBTL06122
High-performance DisplayPort/PCIe Gen2 hex display
multiplexer
Rev. 02 — 16 April 2009
Product data sheet
1. General description
The CBTL06122 is a six-channel (‘hex’) multiplexer for DisplayPort and PCI Express Gen2
applications. It provides four differential channels capable of switching or multiplexing
(bidirectional and AC-coupled) PCI Express Gen2 or DisplayPort signals, using
high-bandwidth pass-gate technology. Additionally, it provides for switching/multiplexing of
the Hot Plug Detect signal as well as the AUX or DDC (Direct Display Control) signals, for
a total of six channels.
The CBTL06122 is designed for high-performance PCI Express Gen2 and DisplayPort
applications. The device is available in two different pinouts (A and B, orderable as
separate part numbers) to suit different motherboard layout requirements.
The typical application of CBTL06122 is on motherboards, docking stations or add-in
cards where the graphics and I/O system controller chip utilizes I/O pins that are
configurable for either PCI Express or DisplayPort operation. The hex display MUX can be
used in such applications to route the signal from the controller chip to either a physical
DisplayPort connector or a PCI Express connector using its 1 : 2 multiplexer topology. The
controller chip selects which path to use by setting a select signal (which can be latched)
HIGH or LOW.
Optionally, the hex MUX device can be used in conjunction with an HDMI/DVI level shifter
device (PTN3300A, PTN3300B or PTN3301) to allow for DisplayPort as well as HDMI/DVI
connectivity.

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 PCB in the thermal pad region.

7. Functional description
Refer to Figure 4 “Functional diagram”.
The CBTL06122 uses 3.3 V power supply. All signal paths are implemented using
high-bandwidth pass-gate technology, are bidirectional and no clock or reset signal is
needed for the multiplexer to function.
The switch position is selected using the select signal (SEL), which can be latched using
the latch enable pin (LE_N). The detailed operation is described in Section 7.1.
7.1 MUX select (SEL) function
The internal multiplexer switch position is controlled by two logic inputs SEL and LE_N as
described below.

The switch position select input signal SEL controls the MUX through a flow-through latch,
which is gated by the latch enable input signal LE_N (active LOW). The latch is open
when LE_N is LOW; in this state the internal switch position will respond to the state of the
SEL input signal. The latch is closed when LE_N is HIGH, and the switch position will not
respond to input state changes on the SEL input.

7.2 Shutdown function
The CBTL06122 provides a shutdown function to minimize power consumption when the
application is not active but power to the CBTL06122 is provided. Pin XSD (active LOW)
puts all channels in off mode (non-conducting) while reducing current consumption to
near-zero.

11. Test information
11.1 Switch test fixture requirements
The test fixture for switch S-parameter measurement shall be designed and built to
specific requirements, as described below, to ensure good measurement quality and
consistency.
• The test fixture shall be a FR4-based PCB of the microstrip structure; the dielectric
thickness or stack-up shall be about 4 mils.
• The total thickness of the test fixture PCB shall be 1.57 mm (0.62 in).
• The measurement signals shall be launched into the switch from the top of the test
fixture, capturing the through-hole stub effect.
• Traces between the DUT and measurement ports (SMA or microprobe) should be
uncoupled from each other, as much as possible. Therefore, the traces should be
routed in such a way that traces will diverge from each other exiting from the switch
pin field.
• The trace lengths between the DUT and measurement port shall be minimized. The
maximum trace length shall not exceed 1000 mils. The trace lengths between the
DUT and measurement port shall be equal.
• All of the traces on the test board and add-in card must be held to a characteristic
impedance of 50 Ω with a tolerance of ±7 %.
• SMA connector is recommended for ease of use. The SMA launch structure shall be
designed to minimize the connection discontinuity from SMA to the trace. The
impedance range of the SMA seen from a TDR with a 60 ps rise time should be
within 50 Ω ± 7 Ω.

13. 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”.
13.1 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.
13.2 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
13.3 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

13.4 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 13 and 14

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.
