1 / 25 page TECHNICAL NOTE High-performance Clock Generator Series DVD-video Reference Clock Generators for Audio/Video Equipments BU2280FV, BU2288FV, BU2360FV, BU2362FV ● Description These clock generators are an IC generating three types of clocks - VIDEO, AUIDIO and SYSTEM clocks – necessary for DVD player systems, with a single chip through making use of the PLL technology. Particularly, the AUDIO clock is a DVD-Video reference and yet achieves high C/N characteristics to provide a low level of distortion factor. ● Features 1) Connecting a crystal oscillator generates multiple clock signals with a built-in PLL. 2) AUDIO clock of high C/N characteristics providing a low level of distortion factor 3) The AUDIO clock provides switching selection outputs. 4) Single power supply of 3.3 V ● Applications DVD players ● Lineup Part name BU2280FV BU2288FV BU2360FV BU2362FV Power source voltage [V] 3.0 ~ 3.6 3.0 ~ 3.6 2.7 ~ 3.6 2.7 ~ 3.6 Reference frequency [MHz] 27.0000 27.0000 27.0000 27.0000 Output frequency [MHz] DVD VIDEO 2 - - - - 1 27.0000 27.0000 27.0000 27.0000 1/2 - - - - DVD AUDIO, CD (Switching outputs) 768fs 36.8640 /33.8688 - - - 512fs 24.5760 /22.5792 24.5760 /22.5792 24.5760 /22.5792 24.5760 /22.5792 384fs 18.4320 /16.9344 - - - 256fs - - - - other - 36.8640 /16.9344 - 36.8640 /16.9344 SYSTEM 768 (48k type) - - - 36.8640 768 (44.1k type) 33.8688 33.8688 33.8688 33.8688 384 (44.1k type) - 16.9344 - 16.9344 Jitter 1σ [psec] 70 70 70 70 Long-term-Jitter p-p [nsec] 8.0 5.0 2.5 5.0 Package SSOP-B24 SSOP-B16 SSOP-B16 SSOP-B16 Sep. 2008 |
