Programmable fiber optic modules



Renesas High-Performance FemtoClock ® 2 Synthesizer


Mouser Electronics now stocks Renesas Electronics FemtoClock ® 2 high-performance clock frequency synthesizers. Offering ultra-low jitter performance of 64fs RMS, these synthesizers can be installed near switches, ASICs, FPGAs, or PHYs that require multiple reference clocks with sub-100fs jitter performance. In addition, these high-performance devices can be used as tunable OTN reference clocks required for OTU3/OTU4 mapping, and can also be used as reference clocks for programmable optical modules.

The Renesas FemtoClock ® 2 synthesizer family includes the RC22504A synthesizer and the RC32504A jitter attenuator and synthesizer. These devices can also be used as DCOs for frequency margining or OTN clocking applications. The PLL cores of these devices contain fractional feedback analog PLLs (digital PLLs are optional for the RC32504A device) and operate with crystals with frequencies between 25MHz and 80MHz.
FemtoClock ® 2 synthesizers feature four differential outputs or eight LVCMOS outputs, supporting any frequency from 10MHz up to 1GHz (up to 180MHz using LVCMOS). With customer-definable internal one-time programmable memory, these versatile synthesizers automatically configure after reset to use up to four different configurations.
The evaluation platform for the FemtoClock ® 2 synthesizer is the RC22504A evaluation kit. Engineers can use Renesas RICBox software to develop configurations, which are then uploaded to the evaluation board via a USB connection. The evaluation kit is equipped with a Renesas low-noise power regulator and a Renesas low-noise fan-out buffer.
