Overview
The FS453LF, FS454LF, FS455LF, and FS456LF are TV encoders designed for applications which require Component Video, VGA, or RGB output capabilities. The FS45X family can accept digital video or computer graphics in many different resolutions and rates, and convert them to high quality analog video,The FS45x familiy was specifically designed for devices requiring high quality video output. The FS45X family accepts various data inputs, including RGB, and YCrCb, through a programmable digital input interface that supports 24/18/16/12/8 bit pixel data lengths. Ouput resolutions from NTSC (720X480) to 1080i can be supported with this device.
Image Quality
Advanced 2D Flicker Filter: Summit Semiconductor's patented filtering technique reduces flicker to maintain text readability even with small Asian fonts, web pates, presentations, and movies. This filter technology is significantly more effective than typical three-line-average flicker filters.
Scaling: Summit Semiconductor's scaling technology provides finely adjustable, artifact-free scaling independently in X and Y scale to allow perfect sizing of the output to any television. The FS45x encoders can display an image accurately while perfectly sizing the image on the TV, without missing lines causing luma distortions, or color shifts. The FS45X scaling engine can support conversion of VGA to 720P input resolutions to NTSC or PAL TV video outputs.
Color Conversion: Y-notch and C-bandpass filters are built into the FS45x family to prevent color rainbows and bleeding on NTSC composite TV
Power
The FS45x family was designed with low power battery operation in mind. Significant design considerations were made to give full programmable detection and control to minimize power consumption. In its minimum configuration with clocks, DACs, and PLLs turned off, only the serial i/o remains active to allow device re-activation.
Packages
The FS45x family is available both in a 7mmX7mm FBGA package (FS455LF, FS456LF), and 14mm x 14mm, 80 pin PQFP package (FS453LF, FS454LF)
