realtek rtd2523/2513 11 4. functional description 4.1 input digital input (itu 656) rtd is designed to connect the interface of digital signal from video decoder. input data is latched within a capture window defined in registers. the timing scheme designed for input devices are showed in the following diagram. there are not h sync v sync signals provided by the video decoder with itu bt.656, these synchronal signals have to be generated by decoding the eav & sav timing reference signals. xxxu0y0v0y1u2 vgbclk vgb_r(byte) figure 4 input yuv 4:2:2(8-bits) timing only 254 of possible 256 8-bit words may be used to express a signal value, 0 and 255 are reserved for data identification purposes. video 8 data stream is as below: blanking period timing reference code 720 pixels yuv 422 data timing reference code blanking period ? 80 10 ff 00 00 sav cb0 y0 cr0 y1 cb2 y2 ? cr718 y719 ff 00 00 eav 80 10 ? cbn: u(b-y) colour difference component yn : luminance component crn: v(r-y) colour difference component sav/eav format bit 7 bit 6(f) bit 5(v) bit 4(h) bit 3(p3) bit 2(p2) bit 1(p1) bit 0(p0) 1 field bit 1 st field f=0 2 nd field f=1 vertical blanking bit v=1 active video v=0 h=0 in sav h=1 in eav protection bits hardware can recognize the occurrence of eav & sav by detecting the 0xff , 0x00 , 0x00 data sequence, and then generate the hsync vsync field signals internally by decoding the fourth word of the timing reference signal(eav sav). f & v change state synchronously with the eav(end of active video) reference code at the beginning of the digital line. bits p0, p1, p2, p3, have states dependent on the states of the bits f, v and h as shown below. at the receiver this permits one-bit errors to be corrected and two-bits errors to be detected.

realtek rtd2523/2513 17 4.5 auto-adjustment there are two main independent auto-adjustment functions supported by rtd, including auto-position & auto-tracking. the operation procedure is as following; auto-position 1. define the rgb color noise margin (7b,7c,7d): when the value of color channel r or g or b is greater than these noise margins, a valid pixel is found. 2. define the threshold-pixel for vertical boundary search (7c[1:0]). 3. define the boundary window of searching (75 ~ 7a) for horizontal boundary search. 4. start auto-function (7f[0]) . 5. the result can be read from register (80 ~ 87). auto-tracking 1. setting the control-registers (7f) for the function (auto-phase, auto-balance) according to the control-table. 2. define the diff-threshold (7e). 3. define the boundary window of searching (75 ~ 7a) for tracking window. 4. start auto-function (7f[0]) . 5. the result can be read from register (88 ~ 8b). 4.6 pll system inside the rtd, there are three pll systems for display clock and adc sample clock. dclk pll pll provides a wide range of user-programmable frequency synthesis options, and the formula as following; the frequency before vco_divide must be 50mhz~450mhz. dclk = fin * dpm / dpn / vco_divide, meanwhile, fin = 24.576mhz, the dpll_m[7:0] & dpll_n[5:0] are the 8-bit m & 6-bit n value of dclk. dpm=dpll_m[7:0]+2, dpn=dpll_n[5:0]+2. of course, you can force this clock from external oscillators through pins refclk for your own applications. clk pll refclk1 control bit0 internal clk control bit1 figure 11 pll system control diagram spread-spectrum function is also build in dclk to reduce emi while using tcon. you can control the ssp_i, ssp_w, and fmdiv to fine-tune the emi.
