Clock generator for video CD systems
BU2173F
The BU2173F is an IC that generates the CPU clock signal, system clock signal and video clock signal used in video
CD systems. A single crystal resonator can generate three different oscillation frequencies.
Applications
Video CD systems
Features
1) Three frequency clock signals can be generated
with a single attached crystal resonator.
2) Two internal PLL channels.
3) Internal loop filter, eliminating the need to attach a
loop.
4) Single 5.0V power supply.
5) SOP 18-pin package.
