BU2294AF Datasheet | Unknown Manufacturer

Description The BU2294AF is an IC which produces dual clocks required for a game machine from an external crystal oscillator for PAL and a 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. Dimension (Units : mm) SOP8 Features 1) Available with three output clock signals required for a game machine in one chip. 2) All output with low jitter, high S/N 3) No need for additional ponents, Built-in a PLL loop filter 4) 3.3V single power supply Applications Game machines March, 2000 Absolute Maximum Ratings (Ta=25˚C) Parameter Power supply voltage Power dissipation Operating temperature range Storage temperature range Symbol VDD Pd Topr Tstg Limits +3.0 ~ +3.6 450 - 5 ~ +70 - 30 ~ +125 - Unit V m W ˚C ˚C - Derating : 4.5m W/˚C for operation above Ta=25˚C.
