TCXO Specification IQXT-318 ISSUE 1; January 2016 Outline (mm) Description The IQXT-318 uses ASIC technology and is designed to meet the short and medium term stability requirements of packet network synchronisation for Small Cells. The oscillator has low jitter to meet network interface requirements (e.g. 10GE) and low phase noise to meet radio interface requirements of LTE-A (TS 36.104) and WCDMA (TS 25.104) transceivers. The IQXT-318 is the ideal choice for Small Cell synchronisation requirements. FEATURES: Patented ‘varactor linearisation’ removes the effects of tilt when using voltage control. HCMOS and Clipped Sinewave output options available. LTE phase noise compliant. Temperature sensor option. APPLICATIONS: Small Cells WCDMA LTE LTE‐A Standard Frequencies: 19.20MHz, 25.0MHz, 24.5760MHz, 26.0MHz, 30.720MHz, 38.40MHz and 40.0MHz.
