Automotive SerDes Video LinkISL76321 - 16(+3)-bits, 6 to 45MHz Pixel Clock SerdesISL76341 - 24(+3)-bits, 6 to 45MHz Pixel Clock Serdes
A simple, low overhead solution to video data transmission in the car. Intersil's SerDes enables transmission of video data together with bi-directional control down a single shielded twisted pair (STP) cable. The ISL76321/41 are the only products in their class to use a transceiver at both cable ends allowing on-demand, primary data direction change.
These SerDes links offer user flexibility through their I2C programmability, including 16 levels of cable equalization and pre-emphasis. A unique fast locking circuit at the receiver ensures excellent link performance even when exposed to considerable noise.
Key Features• Tx pre-emphasis and Rx-equalization
- Allows for longer cable runs and/or cable cost optimization - EQ provides maximum cable drive capability whilst minimizing EMI
• Unique back-channel solution - Allows low cost end-to-end control data communication - I2C control interface with four I2C addresses
• Unique transceiver design - Reduces inventory management
• Superior line rate locking performance - Ensures continuous video transmission in the face of noise
• Hot-plugging with automatic re-lock with every Hsync• DC balanced line coding via 8B/10B allows AC coupling• 48 Ld QFN package

Ambient Light Sensors
Digital Ambient Light SensorISL76683
Digital Ambient Light SensorThe ISL76683 is an integrated light sensor with an internal integrating ADC intended for automotive applications. The ADC provides 16-bit resolution and is capable of rejecting 50Hz and 60Hz flicker from artificial light sources. The ISL76683 is packaged in a tiny 6 pin package with the benefit of its digital interface offers both programmable features and a robust, low cost link to a microcontroller.
Ambient Light Sensor ISL76671
Low Light optimized Ambient Light SensorOffered in a tiny 4.2mm2 package the ISL76671 will measure incident light levels to lower than 0.01 lux. As such, it's an ideal solution for light detection when hidden behind darkened glass and plastic bezels in a wide range of light based control applications. With temperature compensation and excellent IR rejection, the ISL76671 is an economic and easy to use alternative to other forms of optical sensors such as photo diodes & transistors as it can be directly connected to an ADC sampling system.

LCD Controller TW8819
Low-Cost LCD Controller Solution (for RCD applications)
Key Features• Supports analog CVBS input (4 single ended or 2
differential)• Panel output support 24-bit & 18-bit TTL up to WSVGA
resolution - Also supports TCON and Serial (8-bit) RGB panel outputs
• Font OSD with 256 font RAM / 512 display RAM (4 windows)• Short diagnostics & image enhancement built-in• 48 Ld QFN package (wettable flanks QFN available)• -40°C to +105 °C
The TW8819 is an ultra low-cost highly integrated LCD controller targeting basic Rear Camera Display (RCD) applications. It combines a high quality 2D comb NTSC/PAL/SECAM video decoder, a powerful H/V scaler, font based OSD engine, and image enhancement functions. TW8819 supports differential and single-ended analog composite video inputs and the output supports a wide variety of digital LCD panel types.
Video Converter TW8809
Digital RgB to BT.656 Format Converter with Scaling & Progressive output
Key Features• Supports digital input: YCbCr / 24-bit RGB up to 720p
resolution• Supports analog CVBS input (2 single ended or 1
differential)• Output support: ITU-R BT.656 (interlaced or progressive) up
to SVGA resolution• Font OSD with 256 Font RAM / 512 display RAM (4 windows)• Short diagnostics• 56 Ld QFN package (wettable flanks QFN available)• -40°C to +105°C
The TW8809 is a low cost video format converter that can convert either analog CVBS or 24-bit digital RGB format video and output these signals in ITU-R BT.656 format. The video sources can be scaled and de-interlaced so that the ITU-R BT.656 output is already formatted to the desired resolution and can be either progressive or interlaced format. In addition, TW8809 has a built-in font OSD engine as well as image enhancement capabilities.

Audio Amplifier Boosters
Power Conversion Applications
POWER CONVERSION APPLICATIONSAudio Amplifier Boosters • High Power Controllers and FET Drivers
30 Intersil Automotive Products • 2013 • www.intersil.com
Automotive OEM brands are increasingly turning to audio as one tool to win customers over with. However, packing multi-channel sound into a limited space has forced renewed focus on techniques to improve amplifier efficiency and power densities. This has fed an increasing interest in new amplifier topologies including wider adoption of Class D switching amplifiers. Intersil is helping this activity by developing multi-phase power boosters to increase efficiency of these audio solutions.
When designing high performance audio amplifiers using the supposedly efficient class D architecture, achieving high efficiency is not automatic especially at nominal listening levels. With a traditional fixed supply voltage, power dissipated in the output stages can be pretty significant as illustrated by the red shading in figure 1. However, dynamically modulating the voltage supplied to the power stage
Audio Amplifier Power Boosting with ISL7822x
Advantages of Envelop Tracking
•Reduced average amplifier power dissipation (irrespective of using digital or linear amplifier topologies)
•Significantly reduces power stage heat sinking and thus weight and space

Intersil’s ISL78600 and ISL78601 automotive grade Li-Ion battery management and safety monitoring chipset solution is specifically designed to meet the stringent safety, reliability and performance requirements of next generation Hybrid Electric Vehicle (HEV), Plug-in Hybrid Electric Vehicle (PHEV) and Electric Vehicle (EV) applications.
The automotive grade (AEC-Q100), ISL78600 12-cell battery pack manager can be used as a standalone part in ASIL compliant systems or deployed in conjunction with the complimentary ISL78601 for higher ASIL ratings or in systems requiring
an independent backup solution. The solution provides built-in fault detection for all of its major internal functions and detects external faults such as open wire, over- and under-voltage as well as temperature and cell balancing faults to mitigate battery pack failures.
Overall, the highly integrated functionality of the ISL78600 and ISL78601 offers a number of benefits and can significantly reduce the overall battery management costs of HEV/PHEV/EV battery packs and their associated systems.

Designed to support future dual battery power systems now being considered in Europe, this 48/12V bi-directional DC/DC system combines significant power conversion capabilities yet maintains impressive conversion efficiencies above 95%. The system exploits Intersil’s ISL78220/5 multi-phase PWM controllers to provide a high performance converter in a dense form factor. The demonstrator (ISL78225EVAL2Z) is capable of supplying 1.5kW using a 4-phase configuration (ISL78225). In fact, the modular PWM controllers can easily be exploited to develop conversion designs up to 4kW.
