EL1883 Functional Diagram
Description
The EL1883 video sync separator is manufactured using Elantec's high performance analog CMOS process. This device extracts sync timing information from both standard and non-standard video input and also in the presence of Macrovision pulses. It provides composite sync, vertical sync, burst/back porch timing, and horizontal outputs. Fixed 70mV sync tip slicing provides sync edge detection when the video input level is between 0. 5VP-P and 2VP-P (sync tip amplitude 143mV to 572mV). A single external resistor sets all internal timing to adjust for various video standards. The composite sync output follows video in sync pulses and a vertical sync pulse is output on the rising edge of the first vertical serration following the vertical pre-equalizing string. For non-standard vertical inputs, a default vertical pulse is output when the vertical signal stays low for longer than the vertical sync default delay time. The horizontal output gives horizontal timing with pre/post equalizing pulses. The EL1883 is available in an 8-pin SO package and is specified for operation over the full -40°C to +85°C temperature range.
Applications
- Video amplifiers

- 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 491 KB an1566 Jan 19, 2004AI-generated Summary: The pages primarily contain detailed schematic diagrams and board layout images for a video fader with digital control using DCP technology. The content includes component placements, circuit connections, and layer views (top and bottom) of the evaluation board. It provides visual guidance for assembling and understanding the video fader circuit but lacks descriptive textual information.
- Application NotePDF 635 KB an1118 Apr 15, 2003AI-generated Summary: The document presents performance curves for the Auto Sync Separator Circuit using the EL1883 in HDTV applications. It details composite video input and output signals, along with horizontal and vertical sync outputs across various video formats such as 720P59, 720P60, 1035129, 1035130, 1080123, 1080124, and 1080125. The figures illustrate outputs both directly from the EL1883 and after processing through the 74HC221 circuit, highlighting signal characteristics and synchronization performance.
- 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.
