The new CM1234 from California Micro Devices is the newest addition to the XtremeESD family that utilizes proprietary PicoGuardTM architecture. It features 8 channels of ESD protection that meet ±15 kV contact discharge and ±20 kV air discharge per the IEC 61000-4-2 standard, while meeting 100-ohm differential impedance matching requirements of HDMITM 1.3a and DisplayPortTM digital video standards. The architecture of the CM1234 integrates inductors with diodes to create fixed point impedance matching for high speed data lines. Unlike traditional ESD solutions, the CM1234 does not create the need for added external inductance to compensate for the capacitance of the protective device-an earlier solution that was both complex and costly. In addition to impedance matching, this device features a 40-percent reduction in peak clamping voltage, a 15- to 40-percent reduction in peak residual current, and straight-through routing for improved PCB layout.
