DS3106  
Line Card Timing IC  
General Description  
Features  
Advanced DPLL Technology  
The DS3106 is a low-cost timing IC for telecom line  
cards. The device accepts two reference clocks from  
dual redundant system timing cards, continually  
monitors both inputs, and performs manual reference  
switching if the primary reference fails. The highly  
programmable DS3106 supports numerous input and  
output frequencies including frequencies required for  
SONET/SDH, Synchronous Ethernet (1G, 10G, and  
100Mbps), wireless base stations, and CMTS  
systems. PLL bandwidths from 18Hz to 400Hz are  
supported, and a wide variety of PLL characteristics  
and device features can be configured to meet the  
needs of many different applications.  
Programmable PLL Bandwidth: 18Hz to 400Hz  
Manual Reference Switching  
Holdover on Loss of All Input References  
Frequency Conversion Among SONET/SDH,  
PDH, Ethernet, Wireless, and CMTS Rates  
Two Input Clocks  
CMOS/TTL Signal Format (125MHz)  
Numerous Input Clock Frequencies Supported  
Ethernet xMII: 2.5, 25, 125, 156.25MHz  
SONET/SDH: 6.48, N x 19.44, N x 51.84MHz  
PDH: N x DS1, N x E1, N x DS2, DS3, E3  
Frame Sync: 2kHz, 4kHz, 8kHz  
Custom Clock Rates: Any Multiple of 2kHz Up  
to 125MHz  
The DS3106 register set is backward compatible with  
Semtech’s ACS8526 line card timing IC. The DS3106  
pinout is similar but not identical to the ACS8526.  
Two Output Clocks  
One CMOS/TTL Output (125MHz)  
One LVDS/LVPECL Output (312.50MHz)  
Two Optional Frame-Sync Outputs: 2kHz, 8kHz  
Numerous Output Clock Frequencies Supported  
Ethernet xMII: 2.5, 25, 125, 156.25, 312.5MHz  
SONET/SDH: 6.48, N x 19.44, N x 51.84MHz  
PDH: N x DS1, N x E1, N x DS2, DS3, E3  
Other: 10, 10.24, 13, 30.72MHz  
Applications  
SONET/SDH, Synchronous Ethernet, PDH, and  
Other Line Cards in WAN Equipment Including  
MSPPs, Ethernet Switches, Routers, DSLAMs,  
and Wireless Base Stations  
Frame Sync: 2kHz, 8kHz  
Simplified Functional Diagram  
Custom Clock Rates: Any Multiple of 2kHz Up to  
77.76MHz, Any Multiple of 8kHz Up to  
311.04MHz, Any Multiple of 10kHz Up to  
388.79MHz
