EL4501 Functional Diagram
Description
Support is limited to customers who have already adopted these products.
The EL4501 is a highly-integrated Video Front End (VFE) incorporating all of the key signal conditioning functions for analog video signals. It provides a flexible front-end interface for analog or analog/digital video sub-systems. The VFE contains a high bandwidth DC-restore, an advanced sync separator and a data slicer with an adjustable threshold, configurable output and power-down mode. The VFE performs restoration of the DC level (blanking level) of a video signal and the recovery of all signal timing necessary for synchronization and control. Additionally, data embedded in the active video or VBI regions of the video signal may be extracted using the flexible data slicer incorporated into the VFE. The advanced sync separator exhibits excellent noise immunity by incorporating a digital brick wall filter and signal qualification algorithm. The DC-restored video amplifier is unity gain stable with an unloaded -3dB bandwidth of 100MHz. The input common mode voltage range extends from the negative rail to within 1. 5V of the positive rail. When driving a 75Ω double terminated coaxial cable, the amplifier can drive to within 150mV of either rail. With 200V/µs slew rate, the amplifier is well suited for composite and component video applications. The VFE operates from a single 5V supply from -40°C to +85°C and is available in a reduced footprint 24 Ld QSOP package.

- Application NotePDF 644 KB an1695 Jan 19, 2004AI-generated Summary: The document explains video synchronization pulses, focusing on bi-level and tri-level sync used in analog and HD video respectively. Tri-level sync reduces DC offset, improving HD signal accuracy. Video signal levels are measured in IRE units, with specific values for sync and blanking levels. It discusses video display concepts such as refresh rate, frame rate, interlaced and progressive scanning, and scan lines. High definition video standards like 720p and 1080i frame rates and refresh rate conversions for film content are also covered.
- Application NotePDF 311 KB an1099 Apr 15, 2003AI-generated Summary: The document outlines important legal disclaimers and usage guidelines for semiconductor products. It emphasizes user responsibility for product design and safety, disclaims liability for damages from misuse, and clarifies intellectual property rights. Products are categorized into Standard and High Quality grades with specific application scopes. Users must comply with environmental, export, and safety regulations and consult Renesas for further information.
- Application NotePDF 320 KB an9738 Jan 10, 2002AI-generated Summary: The content details typical vertical blanking intervals and data formats for video systems using rectangular and square pixels at 525/60 and 625/50 standards. It explains line numbering, field activity (VACTIVE), and blanking periods for odd and even fields. Figures illustrate timing relationships and digital active line starts for these video formats, highlighting synchronization and pixel timing specifics.
- Application NotePDF 250 KB an9764 Aug 20, 1998AI-generated Summary: The document provides important legal and usage disclaimers for semiconductor products, emphasizing user responsibility for design incorporation and compliance with laws. It clarifies that Renesas disclaims liability for damages from improper use, alteration, or reverse engineering. Products are categorized into 'Standard' and 'High Quality' grades with specific application guidelines. Users must follow specified operating conditions and implement safety measures. Environmental and export regulations must be observed. Contact details for Renesas sales offices worldwide are provided for further inquiries.
- Application NotePDF 1002 KB an9759 Aug 20, 1998AI-generated Summary: This section explains key parameters and applications of amplifiers, analog switches, multiplexers, and video crosspoint switches. It details amplifier characteristics such as bandwidth, gain flatness, slew rate, differential gain and phase, output current, and supply voltage. Special amplifier features include output voltage limiting and programmable gain. Analog switches enable high-speed signal routing controlled digitally. Multiplexers select among multiple analog signals for routing or sampling. Video crosspoint switches route multiple video sources to multiple destinations using buffer amplifiers with enable control.
- Application NotePDF 2.79 MB an9644 Aug 15, 1998AI-generated Summary: The document explains composite video separation techniques including color trap filter and comb filter methods. The color trap filter uses a notch filter centered at the color subcarrier frequency to separate chrominance but limits bandwidth and causes cross color artifacts. The comb filter exploits chrominance phase inversion between lines to separate luminance and chrominance, preserving full bandwidth luminance and reducing cross color effects. However, it can produce hanging dots on sharp vertical transitions. PAL video requires additional correction due to different chroma interleaving.
- Application NotePDF 410 KB an9741 Jun 25, 1997AI-generated Summary: The document explains the design and operation of bipolar and CMOS DACs, highlighting their structures, characteristics, and applications. Bipolar DACs use bipolar junction transistors for high speed and output current but consume more power. CMOS DACs employ CMOS transistors and R-2R ladders with bit switches, offering lower power consumption. It discusses DAC output current conversion to voltage, compensation techniques for op amps, and inverted DAC operation. Key DAC errors such as offset, gain, and linearity are detailed with correction methods.
