Cut Down Those Car-Display Costs

A highly integrated, automotive-
grade, TFT-LCD
power-supply IC should
help boost performance
and reduce costs associated with
power 7 to 15in. displays,
according to developer Intersil.
The ISL78010 is AEC-Q100
rated, ISO/TS 16949:2002 compliant,
and operates over the
automotive temperature range
(-40 to +105ºC).
The device provides enhanced
reliability against transients with
its higher voltage capability,
which protects against stray
capacitance and parasitic inductances
caused during switching.
The ISL78010 integrates
sequencing, regulated charge
pumps, 2A FET, and fault protection
for each output channel.
This integration saves on cost
and increases board space, and
the reduced component count
improves a system’s overall
mean time between failure
(MTBF), says the company. In
addition, the ISL78010 has four
accurate output channels.
The ISL78010 is designed to
deliver up to 20V of boost voltage
necessary for mid-size display
panels. It comes in a TQFP
package for improved reliability
against vibration.
Eight-module blade server
comes in 4U rackmount chassis
The Mini ITX OctoBlade Server
features eight Intel Core?2 Duo
processors in a 500mm-deep
4U modular system. Developed
by Sight Systems, the server’s
eight complete computer systems
come in the form of plug-in
modules. Each consists of a
Mini ITX-compliant motherboard,
Intel Core 2 Duo mobile
processor, 1GB RAM DDR2,
and a single 2.5in., 80GB, serial
ATA hard-disk drive. In addition,
optional hot-swap capabilities
are available.
Furthermore, the 19in. chassis
contains an integrated, custombuilt,
distributed power supply
that offers dual redundancy and
a stabilised 15Vdc. It’s used to
power one small integrated dcdc
power supply in each of the
eight modules.
The ac-dc power supply contains
two redundant modules
that serve to enhance performance
speed and ensure continuous
operation in the event of a
power-supply module failure.
Zero-crossover op amp
goes rail-to-rail
It’s the industry’s lowest power
zero-crossover op amp. At least
that’s the claim made by Texas
Instruments about its OPA369,
which features a single-inputstage
architecture. It achieves
rail-to-rail performance without
input crossover, solving the
problem of input offset distortion
due to the change in commonmode
voltage, which is very
prominent in low-voltage, rail-torail
applications.
Combined with 1μA quiescent
current, an SC70 package, and
operation down to 1.8V, the
OPA369 simplifies high-performance
designs in battery-powered,
portable products, says
the company.
The single-input stage architecture
delivers an offset voltage of
750μV over the rail-to-rail input
range and a common-mode
rejection ratio (CMRR) of 100dB
minimum. Other features include
low noise of 120nV/√Hz, gain
bandwidth of 12kHz on 1μA,
input bias current of 50pA maximum,
maximum voltage offset
drift of 1.75μV/°C, PSRR of
94dB, and 1/f noise of
3.6μVp-p (0.1 to 10Hz).
6U VPX switch/router carries
up to 24 GbE ports
A high-density, 6U VPX
Gigabit Ethernet (GbE) multilayer
switch/router board
designed by Curtiss-Wright
Controls Embedded Computing
will find homes in rugged,
embedded aerospace and
defence applications.
The VPX6-684 FireBlade II,
available with 12, 20, or 24
GbE ports and up to 4x10GbE
ports, is suited for system integrators
designing secure highperformance
IPv4/v6 Intra-
Platform Networks. The multilayer
board, which can operate
as either a fully managed or an
unmanaged switch/router, is
particularly beneficial to developers
building Layer 2 or Layer
2/3+ networks.
Spectrum analyser handles
20 Hz to 67 GHz
The R&S FSU67 spectrum
analyser, developed by Rohde
& Schwarz, extends the upper
frequency limit in spectrum
analysis from 50 GHz to 67
GHz. Consequently, this will
eliminate the need for external
harmonic mixers.
Featuring a continuous frequency
range starting from 20
Hz, the FSU67 also performs
harmonics measurements in one
go without requiring any modifications
to the test setup. Other
characteristics of the spectrum
analyser include high measurement
accuracy without unwanted
products, as well as strong
RF performance.
