CM1236
ESD Clamp Array for High
Speed Data Line Protection
Product Description
The CM1236 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 DisplayPort 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 CM1236 also features easily routed “pass−through” pinouts in a
RoHS compliant (lead−free), 16−lead WDFN, small footprint
package.
Features
• ESD Protection for 4 Pairs of Differential Channels
• ESD Protection to:
• IEC61000−4−2 Level 4 (ESD) at ±8 kV Contact Discharge
• IEC61000−4−4 (EFT) 40 A (5/50 ns)
• IEC61000−4−5 (Lighting) 3.5 A (8/20 ms)
• Pass−through Impedance Matched Clamp Architecture
• Flow−through Routing for High−speed Signal Integrity
• Minimal Line Capacitance Change with Temperature and Voltage
• 100 W Matched Impedance for Each Paired Differential Channel
• Each I/O Pin can Withstand Over 1000 ESD Strikes*
• RoHS Compliant (lead−free) WDFN−16 Package
Applications
• DVI, DisplayPort, and HDMI Ports in Notebooks, Set Top Boxes,
Digital TVs, and LCD Displays
• General Purpose High−speed Data Line ESD Protection
*Standard test condition is IEC61000−4−2 level 4 test circuit with each pin
subjected to ±8 kv 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.
