Note : Your Quotation Request will be directed to Rakon.

The RHT1490 series from Rakon are low jitter ultra-stable TCXOs that are available in frequencies from 50 MHz to 204.8 MHz. They deliver world class telecommunications grade stability with a low RMS phase jitter of less than 200 fs (12 kHz - 20 MHz). These oscillators are an ideal reference clock solution for SyncE and packet clock requirements (ITU-T G.826x and G.827x). 

They work with both discrete and integrated IEEE 1588 solutions, providing excellent medium term stability for low loop bandwidth applications. Their ultra-low noise floor performance, combined with system PLL filtering, helps achieve very low system clock RMS jitter numbers. The low jitter is required by reference clocks of physical layer devices for high speed interfaces (40G and 100G applications). The TCXOs have a low close-in phase noise under -120 dBc/Hz at 1 kHz offset for a 122.88 MHz clock, making them ideal for C-RAN radio heads, microwave links and small cell applications. They have the optimal balance between close-in phase noise and the noise floor, making it suited to be the single reference clock to be used for network and air interface applications. Their excellent thermal insulation and airflow resistance, makes the system design highly flexible and are available in a 14.4 mm x 9.2 mm x 4.7 mm package.
