| Industry's First Loss-of-Sync Alarm Fits in a SOT23 Package | | | |
SUNNYVALE, CA -Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX7461, a single-channel loss-of-sync (LOS) alarm that provides composite-video sync detection in NTSC, PAL, and SECAM standard-definition television (SDTV) systems. This stand-alone LOS alarm operates from a single +5V supply while consuming only 1.7mA. The low cost, small size, low power, and advanced detection circuitry make the MAX7461 ideal for security video systems, consumer electronics, and automotive rear-seat entertainment (RSE) systems.
The MAX7461 accepts an AC-coupled composite (CVBS), luma (Y), or sync-on-green (SoG) video signal. When the MAX7461's input pin no longer detects a video sync signal, the device generates an alarm by pulling the open-drain output /LOS\ low. This approach eliminates the need for a microcontroller, unlike the typical competitive solution that needs the microcontroller to monitor the signal. Capable of detecting sync signals as small as 0.13Vp-p, the MAX7461 enhances sync detection with an internal filter that prevents false sync detection by reducing color burst, chroma, and system noise.
The MAX7461 is offered in a space-saving, 3mm x 3mm 5-pin SOT23 package that is 1/3 the size of the nearest competitor (30mm2). The part operates over the extended temperature range (-40°C to +85°C) and prices start at $0.99 (1000-up, FOB USA). | | Lunes, 12 Junio, 2006 - 11:09 | |
