RClamp0524PA
RClamp0522P
Ultra Low Capacitance TVS Arrays
Description Features
Circuit Diagram - RClamp0522P Circuit Diagram - RClamp0524PA
Revision 2/23/2011
RailClamp® TVS arrays are ultra low capacitance ESD
protection devices 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 overvolt-
age caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients).
The RClamp®0522P and RClamp®0524PA 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. The RClamp0522P is designed to protect two
lines, while the RClamp0524PA will protect four lines.
The RClamp0522P is in a 6-pin SLP1610P4 package. It
measures 1.6 x 1.0 with a nominal height of 0.58mm.
The RClamp0524PA is in a 10-pin SLP2510P8 package.
It measures 2.5 x 1.0 with a nominal height of 0.58mm.
The leads are spaced at a pitch of 0.5mm and are fin-
ished 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 capaci-
tance, 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 RClamp0524PA 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 RClamp0524PA. 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
100 Ohms ±15% without any PCB board modification.
Figure 3 shows a typical impedance test result for a
TDR risetime of 200ps using a Semtech evaluation
board with 100 Ohm traces throughout. Measure-
ments were taken using a TDR method as outlined in
the HDMI Compliance Test Specification (CTS). In each

case, the device meets the HDMI CTS requirement of
100 Ohm ±15% with plenty of margin.
Figure 3 shows a typical HDMI 1.3 eye pattern at
1080p resolution. As shown there are no violations of
the eye pattern with RClamp0524PA in the circuit. The
RClamp0524PA may also be used to protect the
remaining lines (I2C, CEC, and hot plug). Figure 4
shows the complete protection solution.
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.

Protecting MDDI Ports with RClamp0524PA and
RClamp0522P
The small package size and low capacitance of the
RClamp0522P and RClamp0524PA 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
RClamp0524PA 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.
