This single chip solution included a triple-channel ADC, two PLL circuits, one internal On Screen Display (OSD), sophisticated filter and the most advanced scaling engine. The digital or video input can also be supported via analog/digital input ports that implemented in EL7301. The EL7301 captures input RGB graphics signals directly through the use of the internal PLLs. Such signals will then be converted to 8-bit digital data per channel. The output frequencies range is up to the resolution of SXGA with very small jitter (typically equal to 800ps). Such advantage surely provides high degree of flexibility and display quality for users while setting different level of resolution Figure : EL7301 system block diagram application in dual interface NTSC/PAL/ SECAM VD[23:0] Video Decoder DVS/DHS DDE/DCLK R/G/B H-sync/V-sync AD[7:0] Controls CS PLL Host I/F 1 25 MHz X'tal PD[47:0] PHS/PVS/PDE Triple ADC SoG Processor MPU X'tal_I Deinterlacer EL7301 Core PLL OSD PCLK0 PCLK1 R/G/B Optional External OSD TFT Panel EL7301 Features & Applications Analog RGB input: Integrated three channel 8-bit resolution ADCs and pre-amplifiers for analog-RGB up to SXGA 1280 *1024 @ 75Hz On-chip high performance PLLs Sync on Green (SoG) Digital RGB inputs Additional data port support digital or video data input DVI digital input single 24-bit RGB pixel up to 135 MHz Video display through digital input port De-interlace function for video signal 5V-tolerance input pads Auto detection / Auto adjustment Support for H/V sync interrupt and timing measurement function for mode detection Auto-adjustment functions for frequencies, phases, positions and white-balance Engine Advanced scaling algorithm for excellent image quality Programmable independent horizontal/vertical expansion zooming engine for scaling up and scaling down Support for Fidelity mode without frame buffers required.
