Sigma delta Fractional-N PLL Frequency Synthesizer
(3.5GHz single PLL)
MB15E64UV
ꢀDESCRIPTION
The Fujitsu MB15E64UV includes a serial input Sigma delta Fractional Phase Locked Loop (PLL) frequency
synthesizer with fast lock up function. The PLL consists of 3.5GHz sigma delta Fractional-N PLL.
The new package (BCC18) decreases a mount area of MB15E64UV about 50% comparing with the latest package,
BCC20.
MB15E64UV is ideally suitable for digital mobile communications, such as CDMA.
