The output of this stage is used as the feedback for the DC restoration loop. This voltage is generated in the V Ref block. Elcodis is a trademark of Elcodis Company Ltd.

Maximum video level for the OSD window occurs. Proper operation of the LM does require a very.


The output of the V Ref stage goes to a number of blocks in the video section and also to pin When the EHT current is high enough, the current flowing. Using the RSS technique the scope and generator response have been removed from the output rise and fall times. If a lower line rate is used then a longer clamp pulse may be required. Linearity Error is the variation in step height of a 16 step staircase input signal waveform with 0.

LMNA datasheet and specification datasheet. Functional Description LM, giving a high impedance at the output pin. Download datasheet 2Mb Share this page. C compatible, and allows control of all the pa. Black level clamping of the signal is carried out directly on. Any noise injected into pin 21 will appear on the video. A feedback loop is thus established which acts to prevent the average beam current exceeding I ABL.

Page 14 Schematic www. The video inputs are pins 5, 6, and 7. Black level clamping of the signal is carried out directly on. Details on the internal registers are covered in the Interface Registers Section. This pin allows capacitor filtering on the V Ref output and offers an accurate external reference. The LM pre-amp is designed to work in cooperation. The beam current limit circuit application is as. Minimum video level will occur with. The recommended driver for this pre-amp is one of the LMX family.

All functions of the LM are controlled through the I 2 C. Page 13 Functional Description LM, giving a high impedance at the output pin. Registers 00h, 01h, 02h are used for the gain attenuation. EHT supply, current flows from the supply rail through the.

The video and OSD blocks are shown for the red channel in Figure 1.
