... 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) ...

... Subsequent to the ESD/EOS event, both devices must immediately return to their original specifications, and be ready for an additional strike. Any deterioration in parasitics or clamping capability should be considered a failure, since it can then affect signal integrity or subsequent protection capability. (This is known as "multi- strike" capability.) Rev Page www.onsemi.com CM1235 ...

... CM1235 In the CM1235 PicoGuard XS architecture, the signal line leading the connector to the ASIC routes through the CM1235 chip which provides 100Ω matched differential channel characteristic impedance that helps optimize 100Ω load impedance applications such as the HDMI high speed data lines. ...

... Each ESD channel consists of a pair of diodes in series that steer the positive or negative ESD current pulse to either the Zener diode or to ground. This embedded Zener diode also serves to eliminate the need for a separate bypass capacitor to absorb positive ESD strikes to ground. The CM1235 protects against ESD pulses up to ±8kV contact per the IEC 61000-4-2 standard. ...

... CM1235 (PicoGuard XS ESD protector) lowers the peak voltage and clamping voltage by 45% across a wide range of loading conditions in comparison to a standard ESD protection device. indicates that the DUP/ASIC protected by the CM1235 dissipates less energy than a standard ESD protection device. This data was derived using the test setups shown in Figure 4 ...

... CM1235 CM1235 Application and Guidelines As a general rule, the CM1235 ESD protection array should be located as close as possible to the point of entry of expected electrostatic discharges with minimum PCB trace lengths to the ground planes and between the sig- nal input and the ESD device to minimize stray series inductance. ...
