Features

-40^oC to +85^oC

•

Synchronizes with standard telecom system

references and synthesizes a wide variety of

protected telecom line interface clocks that are

•

Provides two DPLLs which have independent

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

and optional hitless reference switching.

Flexible input reference monitoring automatically

disqualifies references based on frequency and

phase irregularities

compliant with Telcordia GR-1244-CORE, GR-253-

CORE, ITU-T G.813, and compatible with ITU-T

G.8261 (formerly G.pactiming)

•

Internal low jitter APLL provides SONET/SDH

clocks including 6.48 MHz, 19.44 MHz, 38.88 MHz,

51.84 MHz and 77.76 MHz, or 25 MHz and 50 MHz

Synchronous Ethernet output clocks

•

Provides 3 sync inputs for output frame pulse

alignment

•

Programmable output synthesizers (P0, P1)

generate general purpose clock frequencies from

any multiple of 8 kHz up to 100 MHz

Jitter performance of <8 ps RMS on the low jitter

APLL outputs, and <20 ps RMS on the

programmable synthesizer outputs.

Provides 8 reference inputs which support clock

frequencies with any multiples of 8 kHz up to

77.76 MHz in addition to 2 kHz

Generates several styles of output frame pulses

with selectable pulse width, polarity, and frequency

Configurable input to output delay, and output to

output phase alignment

Supports IEEE 1149.1 JTAG Boundary Scan
