Circuit Description *. Function Block VG800b Block Diagram A. Interface 1. Power Supply (DC/DC Converter) ICM1 is a current mode switching regulator controller that drives an external N-channel power MOSFET (ICM2) using a fixed frequency architecture (200KHz). It converts a 12V DC input voltage into regulated and stable output voltage of 5V. Pin2 (ITH / RUN) provide a soft start point and run control inputs. During normal operation the voltage on the ITH / RUN pin will vary from 1.19V to 2.
returned to this pin. Pin5 (SW) are switch node connections to inductors. In step-down applications the voltage swing at this pin from a schottky diode (DM1) drops below ground to VIN. Pin6 (TG) is the output of a floating drive for top N-channel MOSFET (ICM2).This is the output of a floating drive with a voltage swing equal to INTVCC superimposed on the switch node voltage SW. Pin1 (SENSE1 - ) connect to the ( - ) input for the current comparator.
3. Image Processor ICM11(gm5020) is an all-in-one image processor for displays with a dual (analog and digital)interface supporting resolutions up to SXGA. It provides integrated ADC/PLL and a DVI compliant TMDS receiver,a high quality zoom and shrink scaling engine,frame rate conversion,an on-screen display(OSD) controller,a microprocessor and many other functions in a single device. This high level of integration enables simple ,flexible, cost effective solutions with fewer required components. .
The external frame buffer provides the storage required for the frame rate conversion process and the integrated OSD. The gm5020 is able to operate with 16Mbit or 64Mbit Synchronous DRAM (SDRAM) devices and/or 16Mbit or 32Mbit Synchronous Graphics RAM (SGRAM) devices. The FRC data bus width is programmable to 32 or 48-bits. Generally, 32 bits is sufficient for XGA and 48 bits is sufficient for SXGA. The gm5020 OSD controller supports both character-mapped and bitmapped modes.
When transmitting, data bits D0 through D27 are each loaded into registers upon the edge of the input clock signal (CLKIN). The rising or falling edge of the clock can be selected by way of the clock select (CLKSEL) terminal. The frequency of CLKIN is multiplied seven times ( ) and then used to unload the data registers in 7-bit slices and serially. The four serial streams and a phase-locked clock (CLKOUT) are then output to LVDS output drivers. The frequency of CLKOUT is the same as the input clock, CLKIN.
5. DDC 2 B ICM6 & ICM7 (24LC21A) can continuously transmit its extended identification, “EDID” using DDC1 communication channel. In addition, the monitor can respond to a requests for EDID, or complete VDIF, to be transmitted using DDC2, level B commands. Pin6 SCL is clock input for DDC 2B, pin5 SDA for data input, and pin7 VCLK is clock input for DDC1.
