Status: In Production
The MAX24605 is a 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 devices can produce frequency-locked APLL output frequencies up to 750MHz and as many as 5 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 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.
