Including the capacitive loading
from the fringe fields to the anti-pads, the differential via impedance is approximately
These low voltage signaling interfaces require very fast rise and fall times not normally achievable with ESD protection devices installed on the signal line because of capacitive loading
Although ICs are available that provide both ESD protection and level shifting for the HDMI high-speed video/audio signal lines, as well as the two control channels, this removes the flexibility for designers to choose the best video/audio-protection IC offering the highest bandwidth and lowest capacitive loading
In order to minimize skew, it is imperative that line lengths and capacitive loading
be matched within the signal pairs and then compared to skew between other pairs to minimize the signal pair to pair skew.
The SP4040-02BTG Series provides market-leading lightning protection with a minimal capacitive loading
of only 2.
As process geometries used in manufacturing baseband and applications processors migrate to increasingly smaller feature sizes, system operating voltages are also becoming lower so that the amount of capacitive loading
on the data lines has become a major concern for handset designers.
In addition to superior ESD protection (O30kV, contact) and surge capability (20A, 8/20s), the SP4061 and SP4062 Series TVS Diode Arrays offer a very low capacitive loading
They typically operate at data rates up to 500Mbps and are extremely sensitive to capacitive loading
Along with superior ESD protection (O30kV, contact) and surge capability (5A, 8/20s), the SP1006 TVS diode array offers minimal capacitive loading
with best-in-class clamping performance due to its low dynamic resistance of only 0.
Any capacitive loading
introduced by protection devices can significantly degrade the signal integrity.
The Agilent N5345A and N5346A active probing solutions with ultralow capacitive loading
(less than 0.
Protecting high speed data ports is particularly challenging as the capacitive loading
introduced by the protection devices can significantly degrade the signal integrity, especially at the increasingly high data rates required by DVI and HDMI.
