MAX24305, MAX24310

5- or 10-Output Any-to-Any Timing ICs

with Internal EEPROM

General Description

Features

♦

Input Clocks

The MAX24305 and MAX24310 are flexible, high-

performance timing and clock synthesizer ICs that

include a DPLL and two independent APLLs. When

locked to one of two input clock signals, the device

performs any-to-any frequency conversion. From any

input clock frequency 1Hz to 750MHz the device can

produce frequency-locked APLL output frequencies up

to 750MHz and as many as 10 output clock signals that

are integer divisors of the APLL frequencies. Input jitter

can be attenuated by an internal low-bandwidth DPLL.

The DPLL also provides truly hitless switching between

input clocks and a high-resolution holdover capability.

Input switching can be manual or automatic. Using only

a low-cost crystal or oscillator, the device can also serve

as a frequency synthesizer IC. Output jitter is typically

0.18 to 0.3ps RMS for an APLL-only integer multiply

and 0.25 to 0.4ps RMS for APLL-only fractional multiply

or DPLL+APLL operation.

For telecom systems, the device has all required

features and functions to serve as a central timing

function or as a line card timing IC. With a suitable

oscillator the device meets the requirements of Stratum

2, 3E, 3, 4E, and 4; G.812 Types I to IV; G.813; and

G.8262.
