BU2360FV DatasheeDatasheett Clock Generator for Audio/Video Equipment BU2360FV General Description Key Specifications BU2360FV is a clock generator IC capable of Part Name BU2360FV generating three types of clocks - VIDEO, AUDIO and SYSTEM clocks that are necessary for DVD player Power Source Voltage V 2.7 to 3.6 systems. It is a single chip solution that uses PLL Reference Frequency MHz 27.0000 technology. Particularly, the AUDIO clock is a DVD VIDEO 1 27.0000 DVD-Video reference and yet achieves high C/N characteristics that have low level of distortion factor. DVD AUDIO, CD Output 24.5760 (Switching 512fs Frequency 22.5792 outputs) MHz Features 768 SYSTEM 33.8688 (44.1k type) Connecting a crystal oscillator generates multiple clock signals from a built-in PLL circuit. Jitter 1 psec 70 AUDIO clock of high C/N characteristics providing Long-term-Jitter p-p nsec 2.5 a low level of distortion factor The AUDIO clock provides switching selection Operating Temperature Range C -25 to +85 outputs.

(If the ICs are not mounted to the printed circuit board, the characteristics of ICs may not be fully demonstrated.) Mount 0.1F capacitors in the vicinity of the IC PINs between PIN 1 (VDD2) and PIN 2 (VSS2), PIN 5 (AVDD) and PIN 6 (AVSS), PIN 11 (DVSS) and PIN 12 (DVDD), respectively. Depending on the conditions of the printed circuit board, mount an additional electrolytic capacitor between the power supply and GND terminal. For EMI protection, it is effective to put ferrite beads in the origin of power to be supplied to the BU2360FV from the board or to insert a capacitor (of not more than 1), which bypasses high frequency desired, between the power supply and the GND. www.rohm.com TSZ02201-0E3E0J500670-1-2 2015 ROHM Co., Ltd.
