NXP ESD protection device
IP4294CZ10
ESD protection for USB 3.0
(SuperSpeed USB) and eSATA data lines
Designed to protect even the most sensitive high-speed differential interfaces, this device delivers
a unique combination of strong system-level ESD protection with an extremely low «line-to-ground»
capacitance, minimal crosstalk, and excellent capacitance matching.
Key features
 Industry’s best overall protection for USB 3.0 system chips
 Extremely low channel capacitance: 0.5 pF (typ)
 Extremely low differential crosstalk: less than -60 dB
@ 2.5 GHz
 Very low dynamic resistance (less than 0.4 Ω) for both
polarities
 RF-optimized DFN2510A-10 (SOT1176) package
Key applications
 USB 3.0 (SuperSpeed), eSATA, SATA, HDMI, DisplayPort,
or other high-speed datalines in:
 Notebook PCs, motherboards, graphic cards
 TVs, monitors
 Hard-disk drives, digital still- and video cameras
(DSC, DVC)
The ICs for high-speed interfaces like USB 3.0 are particularly
susceptible to ESD strikes since they’re popular in portable
applications that are exposed to a wide variety of ambient
conditions. Also, since the interfaces operate at high speeds,
they react quickly to ESD pulses. As a result, they need ESD
protection with extremely low clamping, which can at the same
time support their demanding requirements for signal integrity.
USB 3.0 and eSATA require close line-to-line capacitance
matching to minimize intra-pair skew. Since they transmit and
receive simultaneously, these interfaces also require very low
differential crosstalk. The NXP IP4294CZ10 delivers a line-to-line
capacitance matching of better than 0.05 pF while offering an
extremely low differential crosstalk of less than 60 dB @ 2.5 GHz.
To guard against exposure to ESD pulses during assembly,
the system chips for very fast data lines typically include
integrated ESD protection, commonly with fast snapback.
TLP measurements and several system-level board tests show
that the IP4294 is the only device in the ultra-low-capacitance
segment that can provide these ultra-fast system chips with
the ESD protection against positive and negative pulses they
need.
