PR Newswire (US)
Industry's Only ESD Solution that passes both HDMI(TM) 1.3a
Compliance and 20kV ESD Tests MILPITAS, Calif., April 28
/PRNewswire-FirstCall/ -- California Micro Devices (NASDAQ:CAMD)
today introduced the latest ESD (electrostatic discharge)
protection device in the XtremeESD family utilizing the PicoGuard
XS(TM) architecture, the CM1234. It features 8 channels of ESD
protection that meet + -15kV contact discharge, and + -20kV air
discharge per the IEC61000-4-2 standard, while meeting 100 Ohm
differential impedance matching requirements of the HDMI(TM) 1.3a
and DisplayPort(TM) digital video standards. It is ideal for
digital TVs, LCD displays, notebook computers, set top boxes, and
HD DVD recorders. (Photo:

electronics manufacturers often test to standards greater than 8kV,
particularly on ports easily accessed by consumers such as side and
front mounted digital video ports", stated Joe Salvador, director
of marketing for computing and digital consumer products. "Until
now, there were no ESD protection devices that could meet these
higher levels of protection and still maintain signal integrity at
HDMI(TM) 1.3a data rates." Picoguard XS Impedance Matching The
CM1234 incorporates the recently introduced PicoGuard XS
architecture that integrates inductors with the diodes to create
fixed point impedance matching for high speed data lines.
Traditionally, system designers must compensate for the capacitance
of the ESD protection device by adding external inductance,
eliminating capacitance under the signal traces near the ESD
device, or both. These approaches add complexity and cost, and are
PCB board dependent, limiting the ability to use multiple board
vendors. In many cases, this may not even be possible, particularly
if the capacitance of the device is too high as is typical with
existing 20kV ESD devices. The CM1234 eliminates the need for these
measures, providing matched impedance with no external compensation
or components required. CM1234 -- Increased ESD Protection The
CM1234 provides protection for four pairs of differential channels,
offering ESD protection to IEC61000-4-2 standard + -15kV contact
discharge and + - 20kV air discharge. The integration of inductors
with the ESD diodes provides for improved ESD protection as well as
outstanding signal integrity. Compared with current best in class
ESD diode arrays, the CM1234 offers: -- 40% reduction in peak
clamping voltage -- 15-40% reduction in peak residual current --
100 Ohm differential impedance matching with no external
compensation required -- Straight through routing for improved
layout -- Compact 16 pin TDFN package for reduced board space
