TCXO Specification IQXT-315 ISSUE 1; January 2016 Outline (mm) Description The IQXT-315 uses ASIC technology to provide enhanced frequency versus temperature stability. It also delivers to the industry the lowest jitter achievable from an ultra-stable TCXO. This allows the oscillator to be compliant with various standards including GR-1244, GR-253, G.812, G.813, G.8262 and G.827x. FEATURES: RMS phase jitter down to 0.13ps. Phase noise <‐160dBc/Hz floor. Excellent frequency stability.
