IDT82V3910
Short Form Datasheet
FEATURES
HIGHLIGHTS
• Jitter generation <0.3 ps RMS (10 kHz to 20 MHz), meets jitter gen-
eration requirements of leading PHYs supporting 10GBASE-R,
10GBASE-W, 40GBASE-R, OC-192 and STM-64
• Features 0.5 mHz to 35 Hz bandwidth
• Provides node clock for ITU-T G.8261/G.8262 Synchronous Ether-
net (SyncE)
• Provides node clocks for Cellular and WLL base-station (GSM and
3G networks)
• Provides clocks for DSL access concentrators (DSLAM), especially
for Japan TCM-ISDN network timing based ADSL equipments
• Provides clocks for 1 Gigabit, 10 Gigabit, and 40 Gigabit Ethernet
• Supports clock generation for IEEE-1588 applications
MAIN FEATURES
• Provides an integrated solution for Synchronous Equipment Timing
Source, including Stratum 3, SMC, EEC-Option 1 and EEC-
Option 2 Clocks
• Integrates T4 DPLL and T0 DPLL; T4 DPLL locks independently or
locks to T0 DPLL
• Supports programmable DPLL bandwidth (0.5 mHz to 35 Hz) and
damping factor (1.2 to 20 in 5 steps)
• Supports 1.1X10-5 ppm absolute holdover accuracy and
4.4X10-8 ppm instantaneous holdover accuracy
• Supports hitless reference switching to minimize phase transients
on T0 DPLL output to be no more than 0.61 ns
• Integrates 2 jitter attenuating APLLs to generate ultra-low jitter
clocks
Supports 3 clock modes: SONET, Ethernet, and Ethernet LAN-
PHY
Supports up to two crystal connections, allowing each APLL to
support up to two modes of operation
• Supports input and output clocks whose frequencies range from
1PPS to 644.53125 MHz
Includes 1PPS clock input and output
Provides IN1 and IN2 for 64 kHz + 8 kHz or
64 kHz + 8 kHz + 0.4 kHz composite clocks
Provides IN3, IN4, IN7~IN14 input CMOS clocks whose frequen-
cies range from 1PPS to 156.25 MHz
Provides IN5 and IN6 input differential clocks whose frequencies
range from 1PPS to 625 MHz
Provides OUT1 to OUT5 output CMOS clocks whose frequency
cover from 1PPS to 125 MHz
Provides OUT6,OUT7,OUT10 and OUT11 output differential
clocks whose frequency cover from 25 MHz to 644.53125 MHz
Provides OUT8 for composite clocks and OUT9 for 1.544 MHz/
2.048 MHz (BITS/SSU)
• Provides output clocks for BITS, GPS, 3G, GSM, etc.
• Provides a 1PPS, 2 kHz, 4 kHz, or 8 kHz frame sync input signal,
and a 1PPS, 2 kHz or 8 kHz frame sync output signal
• Internal DCO can be controlled by an external processor to be used
for IEEE-1588 clock generation
• Supports programmable input-to-output phase offset adjustment
• Limits the phase and frequency offset of the outputs
• Supports Forced or Automatic operating mode switch controlled by
an internal state machine. Automatic mode switch supports Free-
Run, Locked and Holdover modes
• Supports manual and automatic selected input clock switch
• Supports automatic hitless selected input clock switch on clock fail-
ure
• Supports three types of input clock sources: recovered clock from
STM-N or OC-n, PDH network synchronization timing and external
synchronization reference timing
• Supports AMI, LVPECL/LVDS and CMOS input/output technologies
• Supports Master/Slave application (two chips used together) to
enable system protection against single chip failure
• Supports Telcordia GR-1244-CORE, Telcordia GR-253-CORE,
ITU-T G.812, ITU-T G.8262, ITU-T G.813 and ITU-T G.783 Recom-
mendations
OTHER FEATURES
• I2C Microprocessor interface
• IEEE 1149.1 JTAG Boundary Scan
• Single 3.3 V operation with 5 V tolerant CMOS I/Os
• 1mm ball pitch CABGA green package
APPLICATIONS
• SMC / SEC (SONET / SDH equipment)
• EEC (Synchronous Ethernet equipment)
• Core and access IP switches / routers
• Gigabit and Terabit IP switches / routers
• Cellular and WLL base-station node clocks
• Broadband and multi-service access equipment
