1 ics for vcr NN3478FAS-A video signal processor mcp ic for south american pal system overview the NN3478FAS-A is a multi-chip package (mcp) ic which integrates a video (south american pal) luminance/chroma ic an3478a and ccd mn3887. by adopting a low frequency comb sys- tem in a chroma signal processing circuit of the y/c signal processor ic, a system cost down has been achieved due to several steps reduction in the ccd circuit. also a record/playback equalizer circuit has been integrated on a luminance signal processing cir- cuit. further, due to addition of normal audio signal record/playback circuit, it made it possible to share a common p board design with hifi equipment for a normal audio signal processing block, thus allow- ing a space saving. also this ic is fully adjustment-free thanks to zener zap adjustment-free technology. features ? supply voltage range: 4.8 v to 5.2 v (875 mw typ.) ? available for 3.58 mhz system y ? ntsc/pal-m/pal-n ? adjustment-free y video output level (recording mode) y video output level (playback mode) y f o frequency: sync. tip frequency y fm deviation y fm level (recording mode) y chroma level (recording mode) y s-vhs/vhs discrimination threshold frequency y white clip level yy (2-stage switch by i 2 c: 190%, 200%) ? normal audio circuit built-in y bias oscillation level adjustment-free ? building in all filters including ccd filter applications ? vcr, camera recorder, video-television hybrid qfh100-p-1420d unit: mm 20.000.20 23.200.30 17.200.30 14.000.20 (0.825) 80 51 130 31 100 81 50 (0.575) 0.65 0.25 +0.10 ?0.05 0.15 +0.10 ?0.05 3.40 max. 0.100.10 1.400.10 3.000.20 1.400.10 seating plane (1.60) 0.800.20 0 to 10 maintenance/ discontinued maintenance/discontinued includes following four product lifecycle stage. planed maintenance type maintenance type planed discontinued typed discontinued type please visit following url about latest information. http://www.semicon.panasonic.co.jp/en/

ics for vcr NN3478FAS-A 31 usage notes 1. be cautious of handling this device because a reverse polarity mounting causes a flow of over-current which is likely to deteriorate its characteristics and damage. 2. a serial control is likely to affect badly the screen. therefore, manage to make a data transfer within v-period. 3. serial data transfer whenever you send one line of data, you have to issue both start and stop conditions. when you want to change a serial mode setting, you have only to transfer one line of the changed data. example: on transferring all two lines of data: start start ack ack ack stop data ack stop data sub address ack ack sub address address address first line of data second line of data maintenance/ discontinued maintenance/discontinued includes following four product lifecycle stage. planed maintenance type maintenance type planed discontinued typed discontinued type please visit following url about latest information. http://www.semicon.panasonic.co.jp/en/
request for your special attention and precautions in using the technical information and semiconductors described in this book (1) if any of the products or technical information described in this book is to be exported or provided to non-residents, the laws and regulations of the exporting country, especially, those with regard to security export control, must be observed. (2) the technical information described in this book is intended only to show the main characteristics and application circuit examples of the products, and no license is granted under any intellectual property right or other right owned by our company or any other company. therefore, no responsibility is assumed by our company as to the infringement upon any such right owned by any other company which may arise as a result of the use of technical information described in this book. (3) the products described in this book are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances). consult our sales staff in advance for information on the following applications: ? special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or malfunction of the prod- ucts may directly jeopardize life or harm the human body. ? any applications other than the standard applications intended. (4) the products and product specifications described in this book are subject to change without notice for modification and/or im- provement. at the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date product standards in advance to make sure that the latest specifications satisfy your requirements. (5) when designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. otherwise, we will not be liable for any defect which may arise later in your equipment. even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (6) comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors (esd, eos, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. when using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
