• Manufacturer Part Number: nbc12439a
• Description: 3.3 V/5 V Programmable Pll Synthesized Clock Generator
• Manufacturer: ON Semiconductor

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
6. 10 MHz is the maximum frequency to load the feedback divide registers. S_CLOCK can be switched at higher frequencies when used as
7. F
8. Maximum frequency on FREF_EXT is a function of setting the appropriate M counter value, 20 v M v 80, for the VCO to operate within
