Clock generator IC
BU2294AF
The BU2294AF is an IC which produces dual clocks required for a game machine from an external crystal oscillator for
PAL and built-in 2-channel PLL. Three kinds of frequencies ; 53.203425MHz, 67.735842MHz and 4.433619MHz can be
outputted with low jitter and high S/N.

An operation is not guaranteed.
In case it is used at Ta=25°C or more, 4.5mW is reduced at every 1°C.
Radiation resistance design is not used.
Power dissipation is measured when BU2294AF is placed on the board.
