Data Sheet

March 2013

Features

Ordering Information

•

Supports the requirements of ITU-T G.8262 for

synchronous Ethernet Equipment slave Clocks

(EEC option 1 and 2)

ZL30143GGG

100 Pin CABGA Trays

ZL30143GGG2 100 Pin CABGA* Trays

*Pb Free Tin/Silver/Copper

•

Supports the requirements of Telcordia GR-1244

Stratum 3 and GR-253, ITU-T G.813, and G.781

SETS

-40 C to +85 C

•

Supports ITU-T G.823, G.824 and G.8261 for 2048

kbit/s and 1544 kbit/s interfaces

•

Internal state machine automatically controls

mode of operation (free-run, locked, holdover)

Meets the SONET/SDH jitter generation

requirements up to OC-48/STM-16

Flexible input reference monitoring automatically

disqualifies references based on frequency and

phase irregularities

Synchronizes to telecom reference clocks (2 kHz,

N*8 kHz up to 77.76 MHz, 155.52 MHz) or to

Ethernet reference clocks (25 MHz, 50 MHz,

62.5 MHz, 125 MHz)

•

Provides automatic reference switching and

holdover during loss of reference input

Supports master/slave configuration and dynamic

input to output delay compensation for

•

Supports composite clock inputs (64 kHz, 64 kHz +

8 kHz, 64kHz + 8 kHz + 400 Hz)

AdvancedTCA

Generates standard SONET/SDH clock rates (e.g.,

19.44 MHz, 38.88 MHz, 77.76 MHz, 155.52 MHz,

622.08 MHz) or Ethernet clock rates (e.g., 25 MHz,

50 MHz, 125 MHz, 156.25 MHz, 312.5 MHz) for

synchronizing Gigabit Ethernet PHYs

•

Configurable input to output delay and output to

output phase alignment

Applications

•

ITU-T G.8262 System Timing Cards which support

1 GbE and 10 GbE interfaces

•

Programmable output synthesizers (P0, P1)

generate telecom clock frequencies from any

multiple of 8 kHz up to 100 MHz

Telcordia GR-253 Carrier Grade SONET/SDH

Stratum 3 System Timing Cards

•

Generates several styles of telecom frame pulses

with selectable pulse width, polarity and frequency

System Timing Cards which supports ITU-T G.781

SETS (SDH Equipment Timing Source)

Provides two DPLLs which are independently

configurable through a serial interface
