PicoGuard XSTM eXtreme Speed ESD Clamp Array For High Speed Data
Line Protection
Features
• ESD protection for 4 pairs of differential channels
• ESD protection to IEC61000-4-2 Level 4 at ±8kV
contact discharge
• Pass-through impedance matched clamp
architecture
• Flow-through routing for high-speed signal integrity
• Minimal line capacitance change with temperature
and voltage
• 100Ω matched impedance for each paired
differential channel
• Each I/O pin can withstand over 1000 ESD strikes*
• RoHS compliant (lead-free) TDFN-16 package
Applications
• DVI ports, HDMI ports in notebooks, set top boxes,
digital TVs, LCD displays
• General purpose high-speed data line ESD
protection
Product Description
The PicoGuard XS (eXtreme Speed) protection family
is specifically designed for next generation deep sub-
micron high speed data line protection.
The CM1233 is ideal for protecting systems with high
data and clock rates or for circuits requiring low
capacitive loading and tightly controlled signal skews
(with channel-to-channel matching at 2% max
deviation).
The device is particularly well-suited for protecting
systems using high-speed ports such as DVI or HDMI,
along with corresponding ports in removable storage,
digital camcorders, DVD-RW drives and other
applications where extremely low loading capacitance
with ESD protection are required.
The CM1233 also features easily routed "pass-
through" pinouts in a RoHS compliant (lead-free),16-
lead TDFN, small footprint package.

*Standard test condition is IEC61000-4-2 level 4 test circuit with each pin subjected to ±8kV contact discharge for 1000 pulses. Discharges are timed at 1 second intervals and all 1000 strikes are completed in one continuous test
run. The part is then subjected to standard production test to verify that all of the tested parameters are within spec after the 1000 strikes.
