Philips Semiconductors Preliminary specification
Triple video driver hybrid amplifier CR7929
FEATURES
• Transition times (10 to 90%) with 45 V (p-p) swing and
C
=10pF:
L
– rise time (typ.) 2.2 ns
– fall time (typ.) 1.9 ns
• Small 11-pin package
• Design optimized for excellent smearing performance
• Gold metallization for highest reliability.
APPLICATIONS
• Top-end colour cathode-ray tube (CRT) monitors with
pixel frequencies up to 300 MHz.
DESCRIPTION
The CR7929 is a 3-channel hybrid RGB-amplifier module
in an11-pin SOT451A package.
Succeeding the s ucces ful CR6927, C R6928 and CR6929
families, the CR7929 is a pin-compatible next step in
high-bandwidth active load amplifiers. Being an active
load, CR7929 combin es a high bandwi dth with a relativ ely
low and constant dissipation. Its optimized design,
together with innovative application recommendations,
ensures excellent smearing performance.
