MAX24605, MAX24610
5- or 10-Output Any-to-Any Clock Multiplier /
Jitter Attenuator ICs
General Description
Features
Input Clocks
The MAX24605 and MAX24610 are flexible, high-
performance clock multiplier and jitter attenuator 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 2kHz 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 glitchless switching between
input clocks and numerically controlled oscillator
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.
