Features
Single chip low cost solution for synchronizing an
Ethernet PHY to a standard telecom clock
Generates an IEEE 802.3 jitter compliant 25 MHz
Gigabit Ethernet output clock
Supports three modes of operation:
Asynchronous Freerun, Synchronous, and
Asynchronous Holdover
Defaults in Asynchronous Freerun mode
In Asynchronous Freerun mode, the DPLL
generates an output clock with a frequency
accuracy equal to frequency accuracy of the
external crystal oscillator (XO) or a low cost
crystal (XTAL)
In Synchronous mode, the DPLL automatically
synchronizes to one of a pre-defined set of
frequencies including 2 kHz, 8 kHz, 64 kHz,
1.544 MHz, 2.048 MHz, 6.48 MHz, 8.192 MHz,
16.384 MHz, 19.44 MHz, 38.88 MHz, 77.76 MHz.
Configurable to accept a 25 MHz input reference
Automatic entry into Asynchronous Holdover
mode when all input references fail
Input reference is manually selectable through the
serial (SPI) interface
Hitless input reference switching
Lock indicator pin
Input reference status monitors
Programmable loop bandwidth of 14 Hz, 28 Hz, or
890 Hz
Applications
Ethernet Line Cards Supporting Synchronous
Transmission
