RXG1490L

Product catalog summary

Overview
Rakon's RXG1490L GHz XO is designed to deliver output frequencies up to 2.2 GHz with ultra-low RMS phase jitter, making it ideal for applications requiring high precision and low noise, such as Optical Coherent Networking and high-speed ADC/DAC/SERDES clocking. The product is also available as a VCXO model, RVG1490L.

Standard Specifications

Frequency Range: 1.0 – 2.2 GHz, available in Sinewave, Differential Sinewave, or LVPECL output types.
Operating Temperature Range: -40 to 85°C.
Frequency Stability: ±70 ppm, accounting for initial calibration, temperature, supply, load variations, and aging over 10 years at 25°C.
Temperature Stability: ±20 ppm over the operating temperature range.
Supply Voltage (VDD): 3.3 V ±5%.
Supply Current: Varies by output type: 70 mA (Sinewave), 80 mA (Differential Sinewave), 120 mA (LVPECL).
Output Power and Swing: Sub-harmonics at -30 dBc, output power at 2 dBm for single sinewave, and differential swing up to 1.6 V for LVPECL.

SSB Phase Noise and RMS Phase Jitter

At 1.096GHz with LVPECL and 2.193GHz with Sinewave, phase noise varies from -97 dBc/Hz at 100 Hz to -149 dBc/Hz at 10 MHz.
Typical RMS phase jitter is 46 fs (10kHz to 20MHz) and 15 fs (12kHz to 20MHz).

Features

Compact SMD package: 14.0 x 9.0 x 3.0mm.
Frequency range from 1 GHz to 2.2 GHz.
Ultra-low RMS phase jitter.
Lower temperature sensitivity compared to SAW oscillators.

Applications

100G/400G Data communications.
High-speed ADC/DAC/SERDES.
Coherent Optical Modules.
