CBTL05023
Multiplexer/demultiplexer switch for Thunderbolt applications
Rev. 5 — 15 July 2013
Product data sheet
1. General description
The CBTL05023 is a multiplexer/demultiplexer switch chip for DisplayPort v1.2 signals
and the control signals of a 10 Gbit/s channel. The 10 Gbit/s channel does not pass
through this switch. This chip provides BIASOUT output control signal, and the
DC-biasing pull-down resistors to facilitate an external 10 Gbit/s channel.
The AUX MUX is a 2 : 1 switch with CA_DETect pin selecting between AUX and DDC
(Direct Display Control) signals.
The DP MUX is a 2 : 1 switch that selects between DPML (DisplayPort Main Link) and
LSTX/LSRX signals.
This chip also includes three control signal buffers: HPDOUT, CA_DETOUT and
BIASOUT.
CBTL05023 is powered by a 3.3 V supply and it is available in 3 mm  3 mm HVQFN24
package with 0.4 mm pitch.
2. Features and benefits
2.1 AUX MUX 2 : 1 switch
 This 2 : 1 switch is controlled by CA_DET signal multiplexing of the 1 Mbit/s
differential AUX and DDC (Direct Display Control) signals
 When CA_DET is HIGH, DDC path is selected
 Differential AUX channel:
 Low insertion loss: 0.5 dB at 5 MHz
 Low return loss: 19 dB at 5 MHz
 Low ON-state resistance: 7.5 
 Bandwidth: 5 GHz
 Low off-state isolation: 75 dB at 5 MHz
 Low crosstalk: 40 dB at 5 MHz
 Common-mode input voltage VIC: 0 V to 3.3 V
 Differential input voltage VID: 1.4 V (maximum)
 DDC channel has DDC_CLK and DDC_DAT I2C signals
 100 kHz 3.3 V voltage swing
 Both AUXIO+ and AUXIO outputs have 900  (20 %) pull-down resistor that is
enabled by the status of the BIASOUT output pin
 These pull-down resistors provide DC bias for the 10 Gbit/s channel

2.2 DP MUX 2 : 1 switch
The DP MUX is a 2:1 switch that is controlled by DP_PD pin multiplexing of a differential
DPML signal and LSTX/LSRX signals
 The DPML (DisplayPort Main Link) runs up to HBR2 data rate of 5.4 Gbit/s
 The low speed DC coupled signals LSTX and LSRX are 3.3 V single-ended signals
that operated at 1 Mbit/s
 5.4 Gbit/s DPML channel:
 Low insertion loss for DP-DPMLO path: 2.0 dB at 2.5 GHz
 Low insertion loss for LS-DPMLO path: 2.0 dB at 2.5 GHz
 Low return loss for DP-DPMLO path: 15 dB at 2.5 GHz
 Low return loss for LS-DPMLO path: 14 dB at 2.5 GHz
 Low ON-state resistance for DP-DPMLO path: 9 
 Low ON-state resistance for LS-DPMLO path: 13 
 High bandwidth: 7 GHz
 Low off-state isolation: 20 dB at 2.5 GHz
 Low crosstalk: 25 dB at 2.5 GHz
 Common-mode input voltage VIC: 0 V to 3.3 V
 Differential input voltage VID: 1.4 V (maximum)
2.3 General
 The input of the HPDOUT (Hot Plug Detect output) buffer is 5 V tolerant
 HPDOUT, CA_DETOUT and BIASOUT buffers
 CA_DET input leakage current < 0.1 A to prevent driving the 1 M pull-down to a
HIGH level
 BIASOUT buffer is able to provide enough current to drive the bias circuit for the
PIN diode path
 BIASOUT buffer can drive up to six sets of bias circuits for the 10 Gbit/s paths
 When AUXIO_EN is LOW or (BIASIN = 0 and DP_PD = 1), this chip is in Sleep mode
 AUXIO+ and AUXIO of AUX MUX are disabled
 CA_DETOUT and HPDOUT buffers are on
 When the chip is in Sleep mode, CBTL05023 consumes < 3.5 mW
 Patent-pending high-bandwidth analog pass-gate technology
 Very low intra-pair differential skew (5 ps typical)
 All channels have back current protection
 All channels support rail-to-rail input voltage
 CMOS input buffer with hysteresis
 Single 3.3 V  10 % power supply
 HVQFN24 3 mm  3 mm package, 0.4 mm pitch, with exposed center pad for thermal
relief and electrical ground
 ESD: 2500 V HBM, 1250 V CDM

Product data sheet
HVQFN24 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.

11. 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”.
11.1 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.
11.2 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
11.3 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

11.4 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 4) 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 21 and 22

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 4.
