Sony CXD3511Q Datasheet

Digital Signal Driver/Timing Generator

Description

The CXD3511Q incorporates digital signal processor type RGB driver, color shading correction, selectable delay line and timing generator functions onto a single IC. Operation is possible with a system clock up to 200 [MHz] (max.). This IC can process video signals in bands up to UXGA standard, and can output the timing signals for driving various Sony LCD panels such as SXGA and XGA.

CXD3511Q

240 pin QFP (Plastic)

Features

• Various picture quality adjustment functions such

as user adjustment, white balance adjustment and

gamma correction

• OSD MIX, black frame processing, mute and

limiter functions

• LCD panel color shading correction function

• Selectable delay line

• Drives various Sony data projector LCD panels

such as SXGA and XGA

• Controls the CXA3512R and CXA3562R sample-

and-hold drivers

• Line inversion and field inversion signal generation

• Supports AC drive of LCD panels during no signal

Power-on and Initialization of Internal Circuit

As for this IC, two systems of supply voltage should be turned on simultaneously. The initialization of the internal circuit should be also performed by maintaining the system clear pin at low during the specified time after setting the supply voltage in the range of recommended operating conditions and stabilizing as shown in the figure below. Keep in mind that the internal circuit may not be initialized correctly if system clear cancellation is performed before the supply voltage is set in the range of the recommended operating conditions.

CXD3511Q

Description of Operation

1. Description of Input Pins

(a) System clear pins (XCLR1, XCLR2 and XCLR3)

All internal circuits are initialized by setting XCLR1 (Pin 27) low. In addition, the internal PLL is initialized by setting XCLR2 (Pin 28) low, and RGB output is initialized (preset) by setting XCLR3 (Pin 29) low. Initialization should be performed when power is turned on. There are no particular restrictions on the initialization order.

(b) Sync signal input pins (HDIN and VDIN)

Horizontal and vertical separate sync signals are input to HDIN (Pin 31) and VDIN (Pin 32), respectively. The CXD3511Q supports only non-inter lace sync signals with a dot clock of 200MHz or less.

(c) Master clock input pins (CLKP/CLKN and CLKC)

Phase comparison is performed by an external circuit and a clock synchronized to the sync signal is input. The master clock input pins have two systems consisting of CLKP/CLKN (Pins 38 and 39) for small-amplitude differential input (center level: 2.0V, amplitude: ±0.4V), and CLKC (Pin 35) for CMOS level input. In addition, be sure to make the number of dot clocks in 1H as even number. Note that if there is an odd number of dot clocks, the internal phase compensation PLL will not operate properly.

(d) Clock selection pins (CLKSEL1 and CLKSEL2)

The master clock input pins can input either the system dot clock or the 1/2 frequency-divided clock. The internal clock path is selected according to CLKSEL1 (Pin 41) and CLKSEL2 (Pin 44).

Symbol

CLKSEL1 CLKSEL2

Input clock selection Clock input pin selection

Function

L CLKP/CLKN input Dot clock input

H CLKC input 1/2 frequency-divided clock input

(e) PLL setting pin (PLLDIV)

PLLDIV (Pin 45) sets the divider setting of the internal phase compensation PLL circuit. Set PLLDIV low when the internal clock frequency is 55 to 100MHz, or high when 27.5 to 55MHz. In addition, note that the frequency of the clock input to the CXD3511Q must be within the phase compensation PLL operating range, even during free running.

(f) RGB signal input pins (R1IN, R2IN, G1IN, G2IN, B1IN and B2IN)

These pins input RGB signals that have been demultiplexed to 1:2. The Red signal is input to R1IN (Pins 176 to 183) and R2IN (Pins 184, 185 and 188 to 193), the Green signal to G1IN (Pins 194 to 196 and 199 to 203) and G2IN (Pins 204 to 208 and 211 to 213), and the Blue signal to B1IN (Pins 214 to 220 and 223) and B2IN (Pins 224 to 231).

(g) OSD signal input pins (R1OSD, R2OSD, G1OSD, G2OSD, B1OSD, B2OSD, YM1, YM2, YS1 and YS2)

These pins input OSD signals that have been demultiplexed to 1:2. The Red signal is input to R1OSD (Pins 232 and 233) and R2OSD (Pins 2 and 3), the Green signal to G1OSD (Pins 236 and 237) and G2OSD (Pins 4 and 5), and the Blue signal to B1OSD (Pins 238 and 239) and B2OSD (Pins 8 and 9). In addition, the YM signal is input to YM1 (Pin 240) and YM2 (Pin 10), and the YS signal to YS1 (Pin 1) and YS2 (Pin 11).

2. RGB Signal and OSD Signal Pipeline Delay

The RGB signal I/O pipeline delay is 54 dot clocks. In addition, the OSD, YM and YS signal pipeline delay is 34 dot clocks. Note that the phase relationship between each clock and the RGB signals is as shown in the figures below. This relationship is the same for the OSD, YM and YS signals.

(h) Black frame block

This block performs processing to fix the blanking period of the video signal to the desired level regardless of the front-end signal processing results. If the number of pixels calculated from the effective period of the video signal to be displayed is less than the number of pixels of the LCD panel on which the signal is to be displayed, the blanking period of the video signal is displayed in the excess pixels. At this time, the displayed blanking period can be fixed to the desired level regardless of the gain and bright adjustment or other picture quality adjustment results by processing with this block. The settings are as follows.

FRM_ON: 1 = Black frame processing ON, 0 = OFF FRM_DAT: Black frame level setting FRM_H1, FRM_H2: Set the black frame horizontal display range in 1-dot units FRM_V1, FRM_V2: Set the black frame vertical display range in 1-line units (All settings shared by R, G and B)

Here, the desired range of the video signal is replaced with 10-bit data (FRM_DAT) by switching the video signal (port 1 and por t 2) and the coefficients using the pulse output from the pulse decoder.

(j) Pattern generator block

This block generates and outputs the set fixed pattern independently of the input signal. This function is valid when PG_ON = 1. When PG_R (G, B)_ON is "0", the signal level goes to 000h respectively for R, G and B. The raster display pattern is displayed in the effective area, and all other display patterns are displayed in the window area. Here, the effective area is set by PG_HST, PG_HSTP, PG_VST and PG_VSTP, and the window area is set by PG_HWST, PG_HWSTP, PG_VWST and PG_VWSTP. The display pattern signal level is set independently for R, G and B by PG_SIG1R (G, B)[9:0] and PG_SIG2R (G, B)[9:0]. Within the effective area, the pattern and non-pattern signal levels can be switched by PG_R (G, B)_SEL. At this time, the signal level outside the effective area goes to 000h. During horizontal ramp, horizontal stair, vertical ramp and vertical stair display, the PG_SIG1R (G, B)[9:0] and PG_SIG2R (G, B)[9:0] settings are invalid.

The display patterns and signal levels are as follows.
