s

Max power consumption: 1.2W

DESCRIPTION

The STV2001 is an I2C-controlled monolithic

integrated circuit assembled in a TQFP44 plastic

package. It combines both a deflection block

(horizontal and vertical, single frequency with very

powerful geometry correction) and a 120MHz

RGB pre-amplifier.
