The Auto Beam Limit control reduces the gain of the. Load resistors are not required and are not used in the test circuit, therefore all.
Looking at the red. Registers 00h, 01h, 02h are used for the gain attenuation. The output of the Buffer Amp goes to the Contrast stage. This is a voltage controlled gain stage which gives no. Minimum video level will occur with both bits set to a zero. The video ml1269na OSD blocks are shown for the red channel in Figure 1. The recommended driver for this pre-amp is one of.
Bits 0 through 2 in register 08 control. Brightness and bias can be. When current is drawn from the EHT supply, some of the.
LMNA datasheet and specification datasheet. The output of the V Ref stage goes to a number of blocks in the video section and also to pin The blocks for both the green and blue channels are not shown; how- ever, they are identical to the red channel.
The LM pre-amp is designed to work in cooperation. Download datasheet 2Mb Share this page. LMNA lm1269nw and specification datasheet Download datasheet. Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation. The IC is I 2 C compatible, and allows control of all the pa- rameters necessary to directly setup and adjust the gain and contrast in the CRT display. Details on the internal registers are covered in the Interface Registers Section.
The OSD signal is. EHT supply, current flows from the supply rail through the. Elcodis is a trademark of Elcodis Company Ltd. This voltage is generated in. These eight bits determine the output voltage of DAC 3. Black level clamping of the signal is carried out directly on. This pin has a very high input impedance and will pick up any high frequency signals routed near it. Details on the internal registers are covered in the.
Human body model, pF discharged through a 1.
Functional Description LM, giving a high impedance at the output pin. The Auto Beam Limit control reduces the gain of the video amplifiers in response to a datadheet voltage proportional to the CRT beam current. Black level clamping of the signal is carried out directly on. Page 14 Schematic www. The external resistor is connected to pin With such a high impedance the DC restoration can appear.
The ABL acts on all three channels. Minimum video level will occur with. All other trademarks are the property of their respective owners. The output of this. All voltages are measured with respect to GND, unless otherwise specified. Maximum video level for the OSD window occurs. The recommended driver for this pre-amp is one of the LMX family.
The LM pre-amp is designed to work in cooperation.
This pin allows capacitor filtering on the V Ref output and offers an accurate external reference. Block and Connection Diagram. Input from signal generator: The video inputs are pins 5, 6, and 7. Using the RSS technique the scope and.
