BU2381FV Datasheet | ROHM

.. Multimedia ICs Clock generator for digital still camera BU2381FV is a high-performance 3-channel PLL IC. PLL circuit generates necessary clocks by inputting standard clocks of crystal oscillator from outside. Changing a connection of wire can generate any clocks required for any applications of users. Jitter and S/N characteristic has achieved almost the same high-quality sound and vision as oscillating module because of optimization of PLL. Frequency can be changed by the internal dividing control. z Applications Digital still camera z External dimensions (Unit : mm) 5.0±0.2 z Features 1) Generate clocks for video output, CDS, USB from standard clock input 2) No external elements required for PLL 3) Standard clocks apply to two kinds of NTSC/PAL 4) Single power supply of 3.3V operating 5) SSOP-B16 small package 6.4±0.3 4.4±0.2 1.15±0.1 0.1 0.15±0.1 0.1 0.22±0.1 SSOP-B16 z Absolute maximum ratings (Ta=25°C) Parameter Applied voltage Input voltage Storage temperature range Power dissipation Symbol VDD VIN Tstg Pd Limits - 0.5 to +7.0 - 0.5 to VDD+0.5 - 30 to +125 450 ∗ Unit V V °C m W ∗Derating : 4.5m W/°C for operating above Ta=25°C ∗An operation is not guaranteed. ∗Radiation resistance design is not used. ∗Power dissipation is measured when BU2381FV is placed on the board. z Remended operating conditions (Ta=25°C) Parameter Supply voltage Input "H" voltage range Input "L" voltage range Operation temperature range Output maximum load Symbol VDD VIH VIL Topr CL Min. 3.0 0.8VDD 0 - 5 - Typ. - - - - - Max. 3.6 VDD 0.2VDD 70 15 Unit V V V °C p F 0.3Min. 1/5 Multimedia ICs z Block diagram Data1a Data1b Data1c 71.877274MHz or 90.314686MHz or 114.54546MHz PLL1 144M 180M 228M 1/2 CLK1 96.016044MHz 1/2 14.318182MHz XTAL_IN...
