The CY2941x/CY2942x is a programmable PLL-based crystaloscillator solution with flexible output frequency options. It is fieldor factory-programmable for any output frequency between15 MHz and 2.1 GHz. Other frequency options can be configuredwith the I2C interface. Using advanced design technology, itprovides excellent jitter performance across the entire outputfrequency range, working reliably at supply voltages from 1.8 Vto 3.3 V for ambient temperatures from –40℃ to +105℃. Thismakes it ideally suited for communications applications (forexample, OTN, SONET/SDH, xDSL, GbE,networking, wirelessinfrastructure), test and instrumentation applications, andhigh-speed data converters. Additionally, the VCXO functionenables use of the CY2941x/CY2942x series in applicationsrequiring a clock source with voltage control, and in discreteclocking solutions for synchronous timing applications.
