• Manufacturer Part Number: BU2365FV
• Description: Clock Generator With Built-in Vcxo
• Manufacturer: ROHM Co. Ltd.

●Reference data (PLL : Long Term Jitter data)
●Reference data (Period-Jitter MIN-MAX
This data represents the output load up to two times as high as the maximum load of each output.
Since the 27-MHz buffer is dependent on the jitter of a clock input, the output is represented by the ratio to the jitter at 50pF.
This data represents Period-Jitter at the 1000th cycle.
