The Si5328 clock multiplier and jitter attenuator, Silicon Labs’ low jitter, frequency-flexible timing solution is optimized for high-speed networking equipment based on the SyncE standard. It boasts an unmatched combination of any-frequency synthesis and jitter performance as low as 263 femtoseconds RMS, addressing the need for ultra-low jitter physical layer reference clocks in Carrier Ethernet switches and routers. Optimized for Ethernet PHYs ranging from GbE to 100 GbE and fully compliant with ITU-T G.8262 SyncE clock requirements, the device is suited for edge routers, multi-service switches, wireless backhaul systems, DSLAMs and GPON/GEPON OLT equipment. Leveraging patented DSPLL technology, the device generates any output frequency ranging from 8 kHz to 808 MHz and from any input frequency from 8 kHz to 710 MHz. The device is also powered by a single 2.5 V or 3.3 V supply and provides selectable output signal formats. Production quantities of the Si5328 are available now in 6 x 6 mm QFN packages, as well as in two speed grades. The Si5328C-C-GM supports clock outputs up to 346 MHz and is priced at $7.50 each/10,000. The Si5328B-C-GM supports outputs up to 808 MHz and is priced at $9.38 each/10,000.
