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 Video Decoder VD[23:0] DV S/DHS DDE/DCL K Deinterlacer X'tal_I 25 MHz X'tal R/G/B Triple ADC SoG Processor EL7301 Core PD[47:0] PHS/PVS/PDE PLL H-sync/V-sync AD[7:0] Controls CS PLL Host I/F PCLK0 PCLK1 TFT Panel MPU OSD R/G/B Optional External OSD 1 EL7301 Features & Applications Analog RGB input: Integrated th...
