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.
