com CM1234 PicoGuard XSTM 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 • ±15kV contact discharge • ±20kV air 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 Product Description The PicoGuard XS (Xtreme Speed) protection family is specifically designed for next generation deep submicron high speed data line protection.
The CM1234 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 CM1234 also features easily routed "passthrough" pinouts in a RoHS compliant (lead-free),16lead TDFN, small footprint package.
• • • • • • Applications • • DVI ports, HDMI ports in notebooks, set top boxes, digital TVs, LCD displays General purpose high-speed data line ESD protection Electrical Schematic Out_1+ Out_1Out_2+ Out_2Out_3+ Out_3Out_4+ Out_4In_1+ In_1In_2+ In_2In_3+ In_3In_4+ In_4- Gnd = 100Ω differential matched characteristic impedance *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 ...
