Rakon has announced the release of the RTH7050PA, a high performance Hybrid TCXO that incorporates Rakon’s proprietary Mercury+™ ASIC. The product features a hybrid technology, where the ASIC has two functionalities, namely temperature compensation and a heated element to keep the temperature of the resonator constant. The oscillator achieves a frequency stability of ±20 ppb over a wide temperature range from -40 to +105°C. Its frequency slope over temperature is as low as 0.5 ppb/°C.
The RTH7050PA uses a high-Q crystal and an in-house quartz manufacturing process, resulting in superior close-in phase noise performance, an all causes stability of ≤ 4.6 ppm/20 years. Nominal frequencies are available from 10 to 50 MHz in a 10 pad, 7.5 x 5.5 mm footprint size.
5G radios and front-haul synchronisation systems use very low bandwidth servos, down to mHz range. To meet the stringent 3GPP air interface requirements for radios and time alignment error requirements stipulated by ITU-T for front-haul routers and switches, frequency references with very good short to medium term performances are essential.
Compared to traditional TCXOs, Rakon’s Hybrid TCXOs offer 10 times the performance of Stratum 3 TCXO in terms of:
The extremely low temperature sensitivity ensures minimal dynamic noise on the low bandwidth system output, across the entire temperature regime. The close-in phase noise performance enables systems to optimise cost performance by rendering second stage phase noise clean up redundant.
Key specifications:
The unique frequency specifications enable the RTH7050PA to meet both 5G network synchronisation and air interface requirements. It is the ideal choice for applications such as 5G RRHs/RRUs, 4G/5G small cells, optical networks and microwave transmission systems.
