Infineon/CYPRESS CY29421FLXIT

The CY2941x/CY2942x is a programmable PLL-based crystal oscillator solution with flexible output frequency options. It is field or factory-programmable for any output frequency between 15 MHz and 2.1 GHz. Other frequency options can be configured with the I²C interface. Using advanced design technology, it provides excellent jitter performance across the entire output frequency range, working reliably at supply voltages from 1.8 V to 3.3 V for ambient temperatures from -40 °C to +105 °C. This makes it ideally suited for communications applications (for example, OTN, SONET/SDH, xDSL, GbE, networking, wireless infrastructure), test and instrumentation applications, and high-speed data converters. Additionally, the VCXO function enables use of the CY2941x/CY2942x series in applications requiring a clock source with voltage control, and in discrete clocking solutions for synchronous timing applications.
