Product Description
The PicoGuard XS protection family is specifically
designed for next generation deep sub-micron high
speed data line protection.
The CM1235 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 CM1235 also features easily routed "pass-
through" pinouts in a RoHS compliant (lead-free),
4.0mm x 1.7mm, 16-lead TDFN, small footprint
package.
