Ascend Frequency Devices is proud to introduce our highest performance temperature-compensated crystal oscillator (TCXO) to date. The T5A series TCXO is capable of providing frequency stability of ±0.1ppm over -20°C to 70°C and ±0.2ppm over -40°C to 85°C in a 7x5mm SMD ceramic package with excellent phase noise performance.

Features:

  • 3.3V or 5.0V supply voltage options
  • Frequency Range from 10MHz to 52MHz
  • CMOS or clipped-sine wave output
  • External control voltage for frequency modulation and improved performance
  • Stratum 3 performance with overall frequency stability requirement of ±4.6ppm for 20 years and 24-hr holdover performance of ±0.32ppm over industrial temperature range
  • Minimal effects on frequency stability generated by loading and power supply variation. At 3.3V with 10% voltage variation, the resulting frequency offset on the TCXO is < ±0.05ppm

Phase noise performance (CMOS output, 26MHz):
-120 dBc/Hz @100Hz offset
-143 dBc/Hz @1k Hz offset

The T5A series TCXO is an optimal solution as reference clocks in wide variety of communication systems, such as cellular base stations, test instruments, wireless back haul and core network equipment. The tight frequency stability performance of the T5A series is similar to that of an OCXO, but with much lower power consumption and smaller form factor.
