〈 3 to 1 Switch 〉HDMI Switch IC



Restores degraded video signals in large screen TVs and monitors

HDMI Switch IC / Buffer ICAmid the variety of full HD devices centered around high-definition broadcast reception

HDMI has emerged as the de facto transmission standard for connecting devices. ROHM has

developed the world’s first HDMI switch IC/buffer IC capable of stable video output – even with

20m long cables. The goal was to provide a monolithic solution integrating specialized circuitry

that restores decayed signal waveforms in large televisions and monitors along with a switch

for HDMI terminal devices.

2008.07 Embedded ideas #03

Stable HDMI transmission, even in large screen TVs and monitorsThe inclusion of HDMI terminals in various locations on TVs

and monitors has become more and more commonplace. This,

along with the increasing size of screens, has in many cases

made the distance between the image processor and the HDMI

receiver farther, resulting in greater noise and EMI generation,

necessitating buffer ICs, especially in large TVs (32″ to 40″ and

above).

Restores degraded video signalsIn many cases cables with lengths far exceeding 10m may be

required for wall mounting thin-screen TVs or installing projectors

on the ceiling. However, the longer the cable transmission length

the greater the RF waveform decay, possibly resulting in incorrect

transmission. In response to this ROHM integrates an equalizer

that restores the deteriorated input waveform to its original state

(Figure 1), enabling compatibility with 20m cables.

HDMI – as easy to use as USBHDMI requires high ESD resistance since it

is an external interface and insertions and

removals are relatively common. ROHM

provides ESD resistance exceeding 10kV

(HBM), reducing the number of components

required.

The future of HDMI switch/buffer ICsAs the number of HDMI-compatible devices increases comes a

demand for more input terminals. ROHM meets this growing need

by providing for a greater number of terminals. Memory is also

integrated for recording image and sound metadata called EDID

(Extended Display Identification Data), contributing to greater

space savings.

1.5V drive MOSFETs for portable devices

ECOMOS™ series

Power MOSFET requirementsPortable device development has reached a point where a dizzying

array of functions is built into a device no bigger than a palm.

‘Compact’, ‘lightweight’, and ‘long battery life’ have become much

more than mere catchwords – they often spell the difference

between success and failure for a portable product in the highly

competitive consumer electronics sector. ROHM offers components

that meet these needs without sacrificing functionality or reliability.

Drastically reduced MOSFET ON-resistance

Ideally, the power consumption for power MOSFETs used as ON/

OFF switches on power supply lines to circuit blocks 0W. However,

this is not the case due to the internal ON-resistance (P(loss)

= RDS(on) × I2). Therefore, reducing ON-resistance is critical for

reducing power consumption. ROHM’s ECOMOS™ series features

a submicron cell pitch structure, developed using microfabrication

technology. This increases current capacity per unit area to

approximately 2.5 times that of conventional products, resulting in

lower ON-resistance. The lineup is offered in several voltage ratings

for optimum compatibility.

Low 1.5V driveConventional ON/OFF switches in 1.5V power lines use step-up

drives with level shift circuits or bipolar transistors to drive 1.8V or

2.5V power MOSFETs, increasing power consumption. However,

ROHM, through process optimization, has achieved a Gate-Source

voltage drive (VGS) of 1.5V, enabling direct drive from 1.5V lines,

reducing not only power consumption but the number of external

components. In addition, using low-voltage drive contributes to a

reduction in the ON-resistance of other drive voltage regions (VGS =

1.8V/2.5V/4.5V), making it is superior to conventional 1.8V and 2.5V

drive power MOSFETs (Figure 1).

Power consumption reduced up

to 60% during ON state

ROHM’s ECOMOS™ is a power MOSFET specifically designed for use in the power circuits of portable devices. Special

emphasis was made to reduce power consumption by significantly reducing ON-resistance during operation for longer

battery life. Every effort was made to minimize environmental impact, including the use of halogen-free resins.

Using ROHM ECO Devices save energy and reduce CO2 generation

Compact, high-power package with high heat resistance

Recently batteries have become more compact and thinner,

while increasingly precise heat design dissipates heat generated

by the power MOSFET outside of the case. In response to this

trend ROHM has developed new compact, high power packages

optimized for battery charge control compatible with several

hundred mW. (Figure 2)

Figure 2. Packages Optimized for Portable Devices

Ideal circuit for portable devicesECOMOS™ offers a variety of advantages to the device designer

when used in various portable device circuitry, such as dual Pch

configuration for switching between the adapter and secondary

lithium ion battery in charge control blocks, or an integrated

Schottky barrier diode for reverse current prevention that simplifies

circuit design.

At ROHM we are involved in minimizing MOSFET voltages as

much as possible, presently to 1.2V and 1V. In addition, continual

progress is being made in the development of SiC (Silicon Carbide)

MOSFETs featuring dramatically lower ON-resistance and

increased voltage resistance.
