<p></p> <p><b>Página nueva</b></p><div>[[Imagen:SN76489.svg|thumb|right|200px|Pinout del Texas Instruments SN76489]]<br /> El Generador Programable de Sonido (PSG) &#039;&#039;&#039;SN76489&#039;&#039;&#039; es un [[chip de sonido]] de cuatro canales compatible [[Tecnología TTL|TTL]] diseñado y fabricado por [[Texas Instruments]]. Su aplicación principal fué la generación de música y [[efectos de sonido]] en [[videoconsola]]s, [[arcade]]s y [[ordenador doméstico|ordenadores domésticos]] (como el [[BBC Micro]], [[Coleco Adam]], [[Sega SC 3000]], [[Memotech MTX-500]], [[SORD M5]] y el [[IBM PCjr]]).<br /> <br /> Las prestaciones del SN76489 eran:<br /> *Tres generadores de tonos programables de [[onda cuadrada]].<br /> *Un generador programable de [[Ruido blanco]]<br /> *[[Atenuación]] programable.<br /> *Salida de sonido Mono<br /> <br /> La [[frecuencia]] de las ondas cuadradas producidas en cada canal se deriva de dos factores : la velocidad del reloj externo y un valor proporcionado en un registro de control para cada canal (llamado N). Cada frecuencia de canal es alamcenada en él dividiendo el reloj por 32 y dividiendo el resultado por N.<br /> <br /> Un núcleo del SN76489 se incluye en el chip [[Graphics Processing Unit|custom VDP]] que [[Sega]] usa en las [[videoconsola]]s [[Master System]], [[Game Gear]], y [[Mega Drive]] ([[Sega Genesis]] en [[Estados Unidos]]). Las funciones básicas son las mismas, pero la aleatoriedad para el canal de ruido blanco se genera de forma diferente, y la implementación en la Game Gear permite la salida de audio estéreo.<br /> <br /> ==Enlaces externos==<br /> *[ftp://ftp.whtech.com/datasheets%20&amp;%20manuals/SN76489.pdf Data Sheet] (Original [[Portable Document Format|PDF]])<br /> *[http://www.howell1964.freeserve.co.uk/parts/76489.htm SN76489 Data Sheet]<br /> *[http://web.inter.nl.net/users/J.Kortink/home/articles/sn76489/ SN76489 Sound Chip Details]<br /> *[http://www.smspower.org/maxim/docs/SN76489.txt SN76489 Notes]<br /> ==Enlaces a Wikipedia==<br /> *{{w|en|Texas_Instruments_SN76489}}<br /> *{{w|es|Texas_Instruments_SN76489}}<br /> *{{w|nl|SN76489}}<br /> <br /> [[Categoría:Chips de sonido]]</div>
