TXC Corp. has released its 7N series of seam sealed surface-mount voltage-control temperature-compensated crystal oscillators (VCTCXOs) that are designed for use in 2-way radios, pagers, and analog applications.

Product frequency stability over temperature is rated at 2.5ppm (-30C to 85C), SSBN is 16.8MHz to 10KHz, and offset is -140dBc/Hz. Other specifications include a nominal frequency of 19.2MHz, a supply voltage of 2.75V 0.1V, RF output of 0.8Vp-p clipped sine wave, and maximum drain current of 1.5mA.

Measuring 5-by-3.2-by-1.5mm, the oscillators feature a frequency adjust center voltage of 1.50Vdc, a frequency adjustable range of 6.5ppm to 11ppm, and aging of 1ppm/yr at 25C.
