  • Page 43 1.5 Operating Modes The Source Clock (also called SCLK in this document) and the Panel Clock are defined as follows: The Source Clock is the sample clock regenerated from the input Hsync timing (called clock recovery) by SCLK DDS (direct digital synthesis) and the PLL. The Panel Clock is the timing clock for panel data at the single pixel per clock rate.
  • Page 44 1.5.4 Downscaling Panel Clock frequency < Source Clock frequency Panel Hsync frequency < Input Hsync frequency Panel Vsync frequency = Input Vsync frequency This mode is used when the input resolution is greater than the panel resolution, to provide enough of a display to enable the user to recover to a supported resolution.

  • Page 46 The SCLK frequency (1/SCLK period) can be set to the range of 10-to-135 MHz. Using the DDS (direct digital synthesis) technology the clock recovery circuit can generate any SCLK clock frequency within this range. The pixel clock (DCLK or destination clock) is used to drive a panel when the panel clock is different from SCLK (or SCLK/2).
  • Page 47 The table below summarizes the characteristics of the clock recovery circuit. Table 7. Clock Recovery Characteristics Minimum Typical Maximum SCLK Frequency 10MHz 135 MHz Sampling Phase 0.5 ns/step, 64 steps Adjustment Patented digital clock synthesis technology makes the gmZAN2 clock circuits very immune to temperature/voltage drift.
  • Page 48 2.3 Analog-to-Digital Converter 2.3.1 Pin Connection The RGB signals are to be connected to the gmZAN2 chip as described in Table 8 and Table 9. Table 8.

  • Page 49 2.3.2 Sync. Signal Support The gmZAN2 chip supports digital separate sync (Hsync/Vsync), digital composite sync, and analog composite sync (also known as sync-on-green). All sync types are supported without external sync separation / extraction circuits. Digital Composite Sync The types of digital composite sync inputs supported are: OR/AND type: No Csync pulses toggling during the vertical sync period XOR type: Csync polarity changes during the vertical sync period The gmZAN2 provides enough sync status information for the firmware to detect the digital composite sync...
  • Page 50 The display start/end registers store the first and the last pixels/lines of the last frame that have RGB data above a programmed threshold. The reference point of the STM block is the same as that of the source timing generator (STG) block: The first pixel: the pixel whose SCLK rising edge sees the transition of the HSYNC polarity from low to high.
  • Page 51 2.5.1 Scaling Filter The gmZAN2 scaling filter uses an advanced adaptive scaling technique proprietary to Genesis Microchip Inc. and provides high quality scaling of real time video and graphics images. This is Genesis’ third generation scaling technology that benefits from the expertise and feedback gained by supporting a wide range of solutions and applications.

  • Page 56 2.6.3 Panel Interface Drive Strength As mentioned previously, the gmZAN2 has programmable output pads for the TFT panel interface. Three groups of panel interface pads (panel clock, data, and control) are independently controllable and are programmed using API calls. See the API reference manual for details. Table 14.
  • Page 57 2.7.1 Serial Communication Protocol In the serial communication between the microcontroller and the gmZAN2, the microcontroller always acts as an initiator while the gmZAN2 is always the target.

  • Page 60 To improve the appearance and make it easy to find the OSD window on the screen, the user may select optional shadowing (3D effect). The “Shadow” feature operates in the same manner as in the B120; that is, it produces a region of half intensity (scaler data) pixels of the same width and height as the OSD window, but offset to the right and down by 8 pixels/lines (the border width setting has no effect).
