MAX24405, M
AX24410
5 or 10 Output Any-Rate Clock Multipliers
General D es cription
The MAX24405 and MAX24410 are flexible, high-
performance clock multiplier/synthesizer ICs with two
independent APLLs. Each APLL performs any-to-any
frequency conversion. From any input clock frequency
9.72MHz to 750MHz these devices can produce
frequency-locked APLL output frequencies up to
750MHz and as many as 10 differential output clock
signals that are integer divisors of the APLL
frequencies. Output jitter is typically 0.35 to 0.5ps RMS
(12kHz to 20MHz) on all outputs and can be as low as
0.24ps RMS. Each device can configure itself from an
external EEPROM so that clock signals are available
immediately after power-up or reset.
