DVD-video Reference
Clock Generators for A/V Equipments
BU2280FV, 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

Common to BU2280FV, BU2360FV and BU2362FV:
*1 Period-Jitter 1σ
This parameter represents standard deviation (1 ) on cycle distribution data at the time when the output clock cycles
are sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
*2 Period-Jitter MIN-MAX
This parameter represents a maximum distribution width on cycle distribution data at the time when the output clock
cycles are sampled 1000 times consecutively with the TDS7104 Digital Phosphor Oscilloscope of Tektronix Japan, Ltd.
*3 Output Lock-Time
The Lock-Time represents elapsed time after power supply turns ON to reach a 3.0V voltage, after the system is
switched from Power-Down state to normal operation state, or after the output frequency is switched, until it is stabilized
at a specified frequency, respectively.
BU2360FV
4 This parameter represents lower and upper limit voltages at the Schmitt trigger input PIN having hysteresis
characteristics shown in figure below. The width requested by these differences is assumed to be a hysteresis width.
