TCVCXO Specification Part No. + Packaging: LFTVXO072344Reel Customer Part: Description Outline (mm) The IQXT-316-7 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-316-7 is the ideal choice for Small Cell synchronisation requirements.
