Ultra Low Capacitance TVS Arrays
Description Features
Circuit Diagram - RClamp0522P Circuit Diagram - RClamp0524P
Revision 03/11/2009
RailClamps® are ultra low capacitance TVS arrays
designed to protect high speed data interfaces. This
series has been specifically designed to protect sensitive
components which are connected to high-speed data
and transmission lines from overvoltage caused by ESD
(electrostatic discharge), CDE (Cable Discharge Events),
and EFT (electrical fast transients).
The RClampTM0522P and RClampTM0524P have a
typical capacitance of only 0.30pF between I/O pins.
This allows it to be used on circuits operating in excess
of 3GHz without signal attenuation. They may be used
to meet the ESD immunity requirements of IEC 61000-
4-2, Level 4 (±15kV air, ±8kV contact discharge). The
RClamp0522P is designed to protect two lines, while
the RClamp0524P will protect four lines.
The RClamp0522P is in a 6-pin, RoHS/WEEE compliant,
SLP1610P4 package. It measures 1.6 x 1.0 with a nomi-
nal height of 0.58mm. The RClamp0524P is in a 10-pin,
RoHS/WEEE compliant, SLP2510P8 package. It mea-
sures 2.5 x 1.0 with a nominal height of 0.58mm. The
leads are spaced at a pitch of 0.5mm and are finished
with lead-free NiPdAu. They are designed for easy PCB
layout by allowing the traces to run straight through the
device. The combination of small size, low capacitance,
and high level of ESD protection makes them a flexible
solution for applications such as HDMI, DisplayPortTM,
MDDI, and eSATA interfaces.

Design Recommendations for HDMI Protection
Adding external ESD protection to HDMI ports can be
challenging. First, ESD protection devices have an
inherent junction capacitance. Furthermore, adding
even a small amount of capacitance will cause the
impedance of the differential pair to drop. Second,
large packages and land pattern requirements cause
discontinuities that adversely affect signal integrity.
The RClamp0524P and RClamp0522P are specifically
designed for protection of high-speed interfaces such
as HDMI. They present <0.4pF capacitance between
the pairs while being rated to handle >±8kV ESD
contact discharges (>±15kV air discharge) as outlined
in IEC 61000-4-2. Each device is in a leadless SLP
package that is less than 1.1mm wide. They are
designed such that the traces flow straight through the
device. The narrow package and flow-through design
reduces discontinuities and minimizes impact on signal
integrity. This becomes even more critical as signal
speeds increase.
Pin Configuration
Figure 1 is an example of how to route the high speed
differential traces through the RClamp0524P. The
solid line represents the PCB trace. The PCB traces
are used to connect the pin pairs for each line (pin 1 to
pin 10, pin 2 to pin 9, pin 4 to pin 7, pin 5 to pin 6).
For example, line 1 enters at pin 1 and exits at Pin 10
and the PCB trace connects pin 1 and 10 together.
This is true for lines connected at pins 2, 4, and 5 also.
Ground is connected at pins 3 and 8. One large
ground pad should be used in lieu of two separate
pads. The same layout rules apply for the
RClamp0522P.
TDR Measurements for HDMI
The combination of low capacitance, small package, and
flow-through design means it is possible to use these
devices to meet the HDMI impedance requirements of
100Ohm ±15% without any PCB board modification.
Figures 3 and 4 show impedance test results for a TDR
risetime of 200ps and 100ps respectively, using a
Semtech evaluation board with 100 Ohm traces
throughout. Measurements were taken using a TDR
method as outlined in the HDMI Compliance Test

Applications Information
Protecting MDDI Ports with RClamp0524P and
RClamp0522P
The small package size and low capacitance of the
RClamp0522P and RClamp0524P make them ideal for
high-speed lines in portable applications. One such
application is the protection of MDDI ports in cellular
phones. MDDI is a serial data interface operating at
480Mb/s per line pair. The lines are scalable for
increased speed and display resolution. A MDDI port
protection example is shown in Figure 5. The
RClamp0524P is used to protect two differential line
pairs while an RClamp0522P is used to protect the
MDDI strobe lines. Note that devices are used on
both the main board and LCD side of the MDDI port.
Devices on the main board are needed to protect the
MDDI controller in the Baseband processor and
devices on the LCD board to protect MDDI controller in
LCD module. A single line TVS such as the
uClamp0501P is used to protect the MDDI power line.
The protection devices should be placed close to the
connector of each board. Traces are routed directly
through each device, minimizing parasitic inductance.
Connections to the ground plane should be made with
multiple micro vias when possible.
Specification (CTS). In each case, the device meets
the HDMI CTS requirement of 100 Ohm ±15% with
plenty of margin.
For signal integrity purposes, the best results will be
obtained by using the RClamp0524P to protect the
high-speed differential pairs. This is because the
device is designed such that the data lines from the
connector line up with the I/O pins of the device
without altering the trace routing. The RClamp0504P
may be used to protect the remaining lines (I2C, CEC,
and hot plug).
Layout Guidelines for Optimum ESD Protection
Good circuit board layout is critical not only for signal
integrity, but also for effective suppression of ESD in-
duced transients. For optimum ESD protection, the
following guidelines are recommended:
zPlace the device as close to the connector as pos-
sible. This practice restricts ESD coupling into
adjacent traces and reduces parasitic inductance.
zThe ESD transient return path to ground should be
kept as short as possible. Whenever possible, use
multiple micro vias connected directly from the device
ground pad to the ground plane.
zAvoid running critical signals near board edges.
