AEL Crystals has made significant improvements to the performance of its VT53 Range of VCTCXOs (voltage compensated, temperature controlled crystal oscillators) primarily aimed at the growing Smallcell market.
Initially available in the frequency range 10 to 26MHz, this range of oscillators are packaged in an ultra-compact 5.0 x 3.2mm format.
The small form factor of the VCTCXOs are rated at +/-100ppb (+/-0.10ppm) stability over a temperature range of 30oC to 65oC; rising to +/-250ppb, +/-0.25ppm when operating at temperatures from -40oC to 80oC.
The company advises these devices have been characterised for use with a wide range of chipsets for femtocell development, to increase a network’s data range and throughput.
In addition to base stations, they can be used in ultra-high stability applications. Stability with respect to load and voltage changes. has been improved to meet +/-10ppb and aging is specified to +/-3.0ppm maximum over 10 years.
The devices are available with clipped sine outputs and offer low power consumption (<2.0mA, <6.0mW typical). They operate from 3.3V and have excellent hysteresis and holdover characteristics.
The company advises it is currently developing the range, by extending the temperature range and reducing input voltage in sampling.
