DS3102

Stratum 2/3E/3 Timing Card IC with

Synchronous Ethernet Support

General Description

Features



Synchronization for Stratum 2, 3E, 3, 4E and 4

plus SMC, SEC and EEC

The DS3102 is a low-cost, feature-rich timing IC for

telecom timing cards. With 8 input clocks, the device

directly accepts both line timing from a large number of

line cards and external timing from external DS1/E1

BITS transceivers. The DS3102 continually monitors all

input clocks and performs automatic hitless reference

switching if the primary reference fails. The T0 DPLL

complies with the Stratum 2, 3E, 3, 4E and 4

requirements of GR-1244, GR-253, G.812 Types I – IV,

G.813 and G.8262. The highly programmable DS3102

support numerous input and output frequencies



Meets Requirements of GR-1244 Stratum 2 – 4,

GR-253, G.812 Types I – IV, G.813, and G.8262

Stratum 2, 3E or 3 Holdover Accuracy with

Suitable External Oscillator



Programmable Bandwidth: 0.5mHz to 400Hz

Hitless Reference Switching on Loss of Input

Automatic or Manual Phase Build-Out

Frequency Conversion Among SONET/SDH,

PDH, Ethernet, Wireless, and CMTS Rates



8 Input Clocks

including

rates

required

for

SONET/SDH,

Synchronous Ethernet (1G, 10G, and 100Mbps),

wireless base stations, and CMTS systems. PLL

bandwidths from 0.5mHz 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. Two DS3102 devices can

be configured in a master/slave arrangement for timing

card equipment protection.



Four CMOS/TTL Inputs (≤ 125MHz)

Four LVDS/LVPECL/CMOS/TTL Inputs

(≤ 156.25MHz)



Three Optional Frame-Sync Inputs (CMOS/TTL)

Continuous Input Clock Quality Monitoring

Numerous Input Clock Frequencies Supported:

SONET/SDH: 6.48, N x 19.44, N x 51.84MHz

Ethernet xMII: 2.5, 25, 125, 156.25MHz

PDH: N x DS1, N x E1, N x DS2, DS3, E3

Frame Sync: 2kHz, 4kHz, 8kHz

The DS3102 register set is backward compatible with

Semtech’s ACS8522 timing card IC. The DS3102 has a

different package and pin arrangement than the

ACS8522.

Custom: Any Multiple of 2kHz Up to 131.072MHz,

Any Multiple of 8kHz Up to 155.52MHz



7 Output Clocks



Three CMOS/TTL Outputs (≤ 125MHz)

Two LVDS/LVPECL Outputs (≤ 312.50MHz)

Two Dual CMOS/TTL and LVDS/LVPECL Outputs

Five CMOS Outputs Have Additional Output Pins

That Can Be Powered at 2.5V or 3.3V

Numerous Output Clock Frequencies Supported:

SONET/SDH: 6.48, N x 19.44, N x 51.84MHz

Ethernet xMII: 2.5, 25, 125, 156.25, 312.5MHz

PDH: N x DS1, N x E1, N x DS2, DS3, E3

Other: 10, 10.24, 13, 30.72MHz

Applications

SONET/SDH Equipment Clocks (SECs)

Synchronous Ethernet Equipment Clocks (EECs)

Timing Card IC in WAN Equipment Including MSPPs,

Ethernet Switches, Routers, DSLAMs, and

Wireless Base Stations


