IP4790CZ38 DisplayPort protection Rev. 01 14 July 2008 Product data sheet 1. General description The IP4790CZ38 is a single chip ElectroStatic Discharge (ESD) protection solution for the DisplayPort interfaces. The low capacitance, typically 0.7 pF to ground, supports the high data rates dened by the DisplayPort interface standard. 2. Features n Robust ESD protection does not degrade even after several discharge incidents n Low leakage, even after several hundred ESDs n Very high ns diode switching speed and low line capacitance (0.7 pF to ground and 0.05 pF between channels) ensures signal integrity n Integrated rail-to-rail clamping diodes with downstream ESD protection of 8kV according to IEC 61000-4-2, level 4 on all Main Link (ML) signal lines n Matched 0.5 mm trace spacing n Optimized TSSOP 38-pin package: u Highly integrated u Small footprint u PCB-level u RF-routing u Lead (Pb) free n Complies with Directive 2002/95/EC, Restriction of Hazardous Substances (RoHS) 3. Applications The IP4790CZ38 can be used with a range of DisplayPort devices including: n Personal computer n PC monitor n Notebook 4. Ordering information Table 1.
