Manufacturer:LINEAR Description:The LTC3548EDD also has an integrated blanking amplifier that takes a positive-going 5V input pulse, VBIN, and outputs a negative-going pulse, VBOUT, with a selectable amplitude of either 20VP-P or 40VP-P via the Pin 13 (S40) option. If Pin 13 is floated, the VBOUT pulse amplitude is 20VP-P; if Pin 13 is grounded, the amplitude is 40VP-P (see Figure 5). With a simple clamp circuit, this inverted pulse can be used to drive the G1 grid of a CRT negative to blank the horizontal retrace lines during the vertical flyback period. The input pulse can be generated from a vertical flyback pulse or by a microcon- troller. The LTC3548EDD can operate with a VCC supply of up to 220V and a selectable VBB supply of either 8V or 12V via the Pin 12 (S12) option. If Pin 12 is floated, then 8V is expected at the VBB pin; if Pin 12 is grounded, then 12V is expected. This VBB option ensures the LTC3548EDD is compatible with any National Semiconductor DTV CRT driver sharing the same operating voltages in the application. Note that using a VBB supply of 12V will increase the input offset of the clamp circuit, which would have the effect of shifting the DC trans- fer function slightly to the right. Also, if the VBB option is incorrectly matched to the actual VBB supply voltage, an incorrect VBOUT amplitude will be produced. Therefore, it is important to ensure that the appropriate VBB option is used and the VBB supply is within the range stated in the Section Operating Ranges . |
