The PE97240 PLL is an integer-N frequency synthesizer that generates multiple output frequencies from a single reference input frequency. It frequency range of 5 GHz in 10/11 prescaler modulus and 4 GHz in 5/6 prescaler modulus. This divided down output enables reference and phase detection at lower frequency, and it handles both frequency and phase lock. The PE97240 achieves an industry-leading maximum FOMfloor of -227 dBc/Hz with the 5/6 prescaler and -225 dBc/Hz with the 10/11 prescaler; the PLL also sets the bar with a FOMflicker of -265 dBc/Hz with the 5/6 prescaler and -259 dBc/Hz with the 10/11 prescaler. The PLL is available in a RoHS compliant, 44-lead, hermetically sealed CQFP package.
