توضیحات
BIT1612 از جمله ايسي هاي ديکودر ويديو با رزولوشن 10 بيتي با OSD and T-CON ميباشد.
از ويژگي هاي عمومي اين ايسي ديکودر ميتوان به نياز نداشتن به حافظه خارجي ، دارا بودن دو مبدل انالوگ به ديجيتال بصورت ديفرانسيل ، نياز داشتن تنها به يک کريستال 24.576 مگاهرتزي،3 ورودي انالوگ ، وروردي هاي RGB 8 بيتي ، پشتيباني از EEPROM سري 24Cxx ، پشتيباني از TWSI ، و پروتکول Bitecbus اشاره کرد.
Description
General:
** No external memory required
** Two 10-bit video CMOS Analog-to-Digital Converters (ADCs) in differential CMOS style for best
S/N-performance
** Fully programmable static gain or automatic gain control (AGC) the selected CVBS or Y/C channel : 0~12db
(Analog) and 0~18db (Digital)
** Automatic Clamp Control (ACC) for CVBS, Y and C
** On-chip clock generator
** L-lock system clock frequencies
** Digital PLL for synchronization and clock generation from all standards and non-standard video sources e.g.
consumer grade VTR
** Requires only one crystal (24.576 MHz) for all standards
** Automatic detection of 50 and 60 Hz field frequency, and automatic switching between PAL and NTSC
standards
** Accepts NTSC (J, M, 4.43), PAL (60, B, D, G, H, I, M, N), and SECAM (B, D, G, K, K1, L) video signal
** User programmable luminance peaking or aperture correction
** Adaptive 3/5-line comb filter for two dimensional chrominance/luminance separation
** PAL delay line for correcting PAL phase errors
