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.
APPLICATIONS:
Stratum 3 / IEEE 1588 / SyncE
SONET / SDH / WDM / OTN
Carrier Ethernet / Microwave
Backhaul / Transport Equipment
Standard Frequencies: 10.0MHz, 12.80MHz, 16.3840MHz,
19.440MHz, 20.0MHz, 20.480MHz, 24.5760MHz, 25.0MHz,

Output Control
Tri-State Mode:
Logic '0' (20%Vs max) to pad 6 disables the oscillator output,
the output goes to a high impedance state.
Logic '1' (60%Vs min) or no connection to pad 6 enables the
oscillator output.
