The PLL locks to the reference and synthesizes frequencies up to 180 MHz on the LVCMOS paths and up to 1 GHz on the differential outputs (CML, HCSL, LVDS, LVPECL). The 2:5 input-to-output ratio gives you one redundant reference input for failover or a clean crystal port, and five outputs you can assign across the differential and single-ended families. The industrial temperature range (-40°C to 85°C) suits base-station, industrial Ethernet switch, and test-equipment clock trees. ## 1 GHz differential outputs — which SERDES lanes it feeds The PLL's jitter performance (not quantified in this listing) is the deciding factor for high-speed SERDES — verify the phase-noise plot in the datasheet against your link budget. ## 24-VFQFPN footprint — layout and thermal notes The 24-VFQFPN (4x4 mm) exposed-pad package requires a thermal via array under the center pad for adequate heat transfer to the ground plane. The pad is electrically connected to the die substrate — typically ground.","metaTitle":"RC22504A000GNK#BB0 FemtoClock Frequency Synthesizer","metaDescription":"Renesas RC22504A000GNK#BB0 FemtoClock frequency synthesizer, PLL with 1 GHz max output, 2:5 fanout, industrial temp, 24-VFQFPN.
