BU2285FV
BU2285FV is an IC which produces plural clocks required for a DVD system from an external crystal oscillator and a
built-in 2-channel PLL. Seven kinds of signals such as 54MHz, 27MHz and 13.5 MHz for a video clock, 33.8688MHz and
16.9342MHz for a CD clock, 33.864MHz and 18.432MHz for a DVD clock can be outputted with low jitter and high S/N.
