TECHNICAL NOTE
High-performance Clock Generator Series
Clock Generator
with Built-in VCXO
for Audio/Video Equipments
BU2365FV
âDescription
The ROHM Clock Generator is an IC allowing for the generation of multiple clocks by a single chip through the connection of
a single crystal oscillator. The BU2365FV incorporates the ROHMâs unique PLL technology to provide the generation of
multiple high C/N clocks necessary for the DVD recorder system. This Clock Generator has the built-in high-precision
VCXO function and allows for high-precision synchronization with DVD Video clocks. It also has a built-in buffer having high
driving force and allows the supply of multiple 27MHz Video clocks for the system, thus providing the reduced number of the
system components.
âFeatures
1) The ROHMâs unique PLL technology allows for the generation of high C/N clocks.
2) Built-in high precision VCXO, which is essential for the DVD recorder system
3) Built-in buffer having high driving force (Load capacity/output CL=50pF, 27MHz drive, 1Ãinput / 2Ãoutputs)
4) Built-in half pulse clock protection [HPC]
5) Built-in power down function, Icc=0 uA(typ.)
6) SSOP-B24 package
7) Single power supply of 3.3 V
