LFTVXO075674CUTT

TCVCXO Specification Part No. + Packaging: LFTVXO075674Reel Customer Part: Description Outline (mm) The IQXT-316-8 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-316-8 is the ideal choice for Small Cell synchronisation requirements.

Output Details Clipped Sine Output Compatibility Drive Capability 10k//10pF Output Voltage Level: 0.8V pk-pk min, 1.1V pk-pk typ Start Up Time (amplitude within 90% of specified output level): 15ms max Temperature Sensor Output (Vtemp on pad 3) Vtemp ( 25C): 1.76V typ Slope Option: -2.1mV/C typ Resistive Load: 100k min Capacitive Load: 30pF max Output Impedance ( 25C): 1k typ Sensor Linearity: 1.5% typ 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. Note: The tri-state control (enable) input pad has an internal 100k pull up resistor which allows it to be left unconnected if not used. When in tri-state mode, the output stage is disabled, but the oscillator and compensation circuit are still active (Current Consumption: 2mA typ). Output Enable Time: 100s max Noise Parameters Phase Noise (typ 25C): -60dBc/Hz 1Hz -90dBc/Hz 10Hz -125dBc/Hz 100Hz -145dBc/Hz 1kHz -153dBc/Hz 10kHz -154dBc/Hz 100kHz -156dBc/Hz 1MHz Phase Jitter (12kHz-5MHz): 210fs RMS typ Sales Office Contact Details: UK: +44 (0)1460 270200 France: 0800 901 383 Email: info iqdfrequencyproducts.com Germany: 0800 1808 443 USA: +1.760.318.2824 Web: www.iqdfrequencyproducts.com Printed on 5 Aug 21 0:05 using Part Data Sheet V1.0018 Page 2 of 3
