Philips Semiconductors
Triple video driver hybrid amplifier
Preliminary specification
CR7929
Rlevel and Rbias are intended to achieve the required output level and to optimize the frequency smearing performance.
Rlevel has to be adjusted to the required output level (approximately 2 kΩ at VS = − 12 V).
Rbias has to be tuned for the best high frequency smearing performance (200 MHz burst).
