World's First, True High-Definition Video Filter Amplifiers From Maxim.SUNNYVALE, Calif. -- Maxim Integrated Products (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :MXIM) introduces the MAX9500/MAX9501, the world's first true high-definition video filter amplifiers and the latest addition the Company's portfolio of video filters and amplifiers. These are the only true high-definition (HD) filter amplifiers because they have greater than 40dB attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. at 44.25MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , which is a requirement for all HD signals sampled at 74.25MHz. Perfect for filtering and buffering HD video signals, the MAX9500/MAX9501 can be used as a reconstruction filter for HD video outputs of set-top boxes, DVD-recorders, DVD players, and satellite/cable receivers. The devices can also be used as an anti-aliasing filter for analog inputs of high-definition televisions (HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates ). Unique Filter Amplifier Capabilities The MAX9500/MAX9501 HD filter amplifiers have three key benefits. 1. Attenuate To reduce the force or severity; to lessen a relationship or connection between two objects. In Criminal Procedure, the relationship between an illegal search and a confession may be sufficiently attenuated as to remove the confession from the protection afforded by the Undesired Aliases Starting at 44.25MHz 2. Drive Two Loads from a Single Set of Outputs 3. Available in Both Single-Supply and Dual-Supply Versions 1. Attenuate Undesired Aliases Starting at 44.25MHz Most MPEG decoders in set-top boxes, DVD players, and AV receivers reconstruct HD video at 74.25MHz. Because, however, HD video signals have a 30MHz bandwidth, there will be a significant alias beginning at 44.25MHz. Therefore, customers need a filter that will pass the baseband video up to 30MHz, but fully attenuate the alias beginning at 44.25MHz. Existing HD filters cannot deliver this needed 30MHz, but instead provide only 15dB attenuation at 44.25MHz (see Figure 1), which allows the unwanted aliases to degrade the video quality. The MAX9500/MAX9501 provide a 30MHz passband pass·band n. The range of frequencies transmitted by a bandpass filter. and 50dB attenuation at 44.25MHz to completely suppress aliases for optimal video quality. 2. Drive Two Loads from a Single Set of Outputs The MAX9500/MAX9501 can drive two loads simultaneously for set-top box customers that have two sets of HD component (Y/Pr/Pb) outputs. Typical ICs only drive one set of outputs which forces customers with two sets of outputs, to TV and recorder for example, to purchase two sets of drivers. The MAX9500/MAX9501 allow customers to drive both loads with the same driver without any degradation of performance. This capability will save both the cost and added space of the additional driver circuitry. 3. Available in Both Single-Supply and Dual-Supply Versions The MAX9500 operates with a single +5V supply for customers that do not have negative a supply rail in their systems. These customers can choose to AC-couple or DC-couple the outputs with a positive DC bias for a very simple solution. The MAX9501 operates with dual +/-5V supplies. This is ideal for customers who already have +/- supplies in their system and do not want to AC-couple the outputs. Most competitors have only single-supply amplifiers so their customers must use a large output capacitor to center the signal around ground. This large coupling capacitor is both expensive and can degrade video quality. Because the MAX9501 operates off +/-5V, the video signal can be centered around ground without any capacitive coupling. The MAX9500/MAX9501 come in compact 5mm x 6mm, 16-pin QSOP QSOP Quarter Size Outline Package QSOP Quarter Small Outline Package QSOP Quad Small Outline Package QSOP Quadripartite Standing Operating Procedures QSOP Quarterly Standing Order Plan QSOP Quality Standard Operating Procedure QSOP Quarter Sized Outline Package and 16-pin SO packages. Lead-free packaging is also available. Prices start at $1.05 (1000-up, FOB FOB 1) adj. short for Free on Board, meaning shipped to a specific place without cost. 2) Friend of Bill (Clinton).
