PicoGuard XS^TMESD Clamp Array For High Speed Data Line Protection

Features

Product Description

•

ESD protection for 4 pairs of differential channels

ESD protection to IEC61000-4-2 Level 4

The PicoGuard XS (Xtreme Speed) protection family is

specifically designed for next generation deep sub-

micron high speed data line protection.

•

15kV contact discharge

20kV air discharge

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).

•

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

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.

•

Applications

•

The CM1234 also features easily routed "pass-

through" pinouts in a RoHS compliant (lead-free),16-

lead TDFN, small footprint package.

DVI ports, HDMI ports in notebooks, set top boxes,

digital TVs, LCD displays

General purpose high-speed data line ESD

protection

Gnd

*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 afterh the 1000 strkes.
