IDT 10G/40G Ethernet Timing IC

IDT 10G/40G Ethernet Timing IC

IDT 82V3910 and 82V3911 are low-jitter, highly-versatile synchronous Ethernet (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. With phase jitter below 300 femtoseconds (fs) RMS over the 10kHz to 20MHz integration range (with all channels in operation), replace multichip alternatives to reduce design complexity and cost.

IDT 82V3910 SyncE Ethernet Timing IC

The 82V3910 is an ITU-T G.8262 compliant synchronous equipment timing source (SETS); its ultra-low jitter generation makes it particularly suitable for single-board systems where the SETS directly times 10G or 40G network PHYs.

Features
  • Single chip solution for SyncE SETS
  • Jitter generation <0.3 ps RMS (10 kHz to 20 MHz) meets the most stringent 10G PHY requirements
  • Two ultra-low-jitter analog PLLs support three clock modes: 622.08 MHz, 625 MHz and 625 MHz x 66/64
  • Generates interface clocks (1GE, 10GBASE-R, 10GBASE-W and 40GBASE-R) and SONET/SDH (OC-192/STM-64)
  • Meets G.8262 for Synchronous Ethernet (SyncE) equipment
  • Meets Telcordia GR-253-CORE & ITU-T G.813 for SONET/SDH equipment
  • Integrates T4 DPLL and T0 DPLLs per ITU-T G.8264
  • Supports input and output clocks whose frequencies range from 1PPS to 625 MHz x 66/64
  • Internal DCO can be controlled by an external processor to be used for IEEE-1588 clock generation
  • Complemented by 82V3911 SyncE PLL for 10GbE and 40GbE

IDT 82V3911 SyncE Ethernet Timing IC

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.

Features
  • Single chip two channel SyncE PLL with hitless reference switching
  • Jitter generation <0.3 ps RMS (10 kHz to 20 MHz) meets the most stringent 10G PHY requirements
  • Two ultra-low-jitter analog PLLs support three clock modes: 622.08 MHz, 625 MHz and 625 MHz x 66/64
  • Generates interface clocks (1GE, 10GBASE-R, 10GBASE-W and 40GBASE-R) and SONET/SDH (OC-192/STM-64)
  • Supports ITU-T G.8262 SyncE compliant equipment
  • Supports Telcordia GR-253-CORE and ITU-T G.813 SONET/SDH compliant equipment
  • Integrates 2 DPLLs, one the transmit path and one for receive path
  • Supports input and output clocks whose frequencies range from 2 kHz to 625 MHz x 66/64
  • Accepts 1 pulse per second (1PPS) sync pulse
  • Complemented by IDT 82V3910 SyncE SETS for 10GbE and 40GbE
  • Integrated Device Technology (IDT)
