World's Lowest Jitter Synchronous Ethernet Timing solutions from IDT

##IMAGE_1_R##Featuring phase jitter below 300 femtoseconds RMS over the 10 kHz to 20 MHz integration range (with all channels in operation), this single-chip device offers 50 percent less jitter than competing solutions and replaces multichip alternatives to reduce design complexity and cost.

The IDT 82V3910 and 82V3911 are low-jitter, highly-versatile SyncE network timing solutions optimized for use in 10GBASE-R/10GBASE-W and 40GBASE-R applications, including switches, routers, multiservice switching platforms, wireless backhaul equipment and other communications infrastructure. The innovative high-integration architecture includes two independent digital PLLs to allow bidirectional synchronization for maximum utility and simplified deployment. The DPLLs lock to a wide variety of telecom and Ethernet reference frequencies and suppress incoming timing faults to generate highly-reliable output clocks for optimal network performance.

“Our latest SyncE network timing devices combine IDT’s industry-leading digital and analog PLL technologies to achieve the first integrated synchronization solution addressing the large and fast-growing market for 10G and 40G applications,” said Christian Kermarrec, vice president and general manager of the Timing and Synchronization Division at IDT. “With jitter less than half that of competing products, the new clocking solutions offer our customers the ultimate in performance and versatility by supporting the most stringent low-jitter requirements found in 10G or 40G Ethernet applications. These devices complement IDT’s rich timing portfolio, including RF and network PLLs, VCXOs, synthesizers, buffers, frequency translators and crystal oscillator replacement products.”

The IDT 82V3910 SyncE SETS simplifies the timing circuit and bill-of-materials by providing the synchronous equipment timing source function to manage all required synchronization timing signals. Ultra-low jitter generation makes the 82V3910 particularly suitable for single-board systems where the SETS directly times 10G or 40G network PHYs. The 82V3910 complies with ITU-T G.8262 for EEC-Options 1 and 2; and G.813 for SEC-Options 1 and 2; and is suitable for SyncE, SONET and SDH equipment. The 82V3910 can synchronize directly to a one pulse per second reference enabling the host system to use a low-cost GPS receiver.

The single-chip 82V3911 SyncE PLL is pre-engineered to select references from a variety of SETS or network sources, perform clock rate conversions, and attenuate jitter – all while preserving the G.8262 compliance of the selected references. Furthermore, the 82V3911 reduces timing circuit BOM cost and board space by providing two PLL channels in a single chip.
