By Sarah RonkoskeNovember 26, 2017

Abracon LLC — a leading supplier of frequency control and magnetic components — offers a complete line of ultra-low jitter solutions that are ideal for applications that require more advanced timing than ever. The high-precision AOCJY6 series of OCXOs, AST3TQ TCXO, AST3TQ53 TCXO, and the temperature compensated ASGTX are perfect for next-generation communications, servers, cloud computing, networking, and RF applications.

Let’s look at the features and benefits of different precision timing solutions.

ASGTX Crystal Oscillators

Abracon’s temperature compensated ASGTX crystal oscillators, introduced in a small form-factor of 9.0x7.0x2.24 mm, are available with either LVPECL or LVDS output, from 10MHz to 1.50GHz, at any required frequency with a solid ±1.00 ppm stability over temperature. 

The high precision crystal oscillators have been designed to cater a wide range of TCXO requirements, without NRE and extended lead-times. Key features of the ASGTX include:

  • 10MHz to 1.50GHz, any Carrier Frequency in differential mode (LVDS or LVPECL)
  • 10MHz to 250MHz, any Carrier Frequency in LVCMOS mode
  • -40ºC to +85ºC operating temperature range
  • ±1.0ppm stability over -30ºC to +70ºC and ±2.0ppm stability over -40ºC to +85ºC
  • Minimum guaranteed pull ability of ± 10 ppm in VCTCXO mode
  • Excellent Phase Noise, excellent Harmonics and Spurious content
  • Assured RMS jitter of 1.80ps maximum @ 1.50GHz carrier (LVDS mode)
  • Instant availability, 5-day maximum lead-time for small quantities
