DESCRIPTION
The LMK04000 family of precision clock conditioners provides low-noise jitter cleaning, clock multiplication and
distribution without the need for high-performance voltage controlled crystal oscillators (VCXO) module. Using a
cascaded PLLatinum architecture combined with an external crystal and varactor diode, the LMK04000 family
provides sub-200 femtosecond (fs) root mean square (RMS) jitter performance.
The cascaded architecture consists of two high-performance phase-locked loops (PLL), a low-noise crystal
oscillator circuit, and a high-performance voltage controlled oscillator (VCO). The first PLL (PLL1) provides a low-
noise jitter cleaner function while the second PLL (PLL2) performs the clock generation. PLL1 can be configured
to either work with an external VCXO module or use the integrated crystal oscillator with an external crystal and
a varactor diode. When used with a very narrow loop bandwidth, PLL1 uses the superior close-in phase noise
(offsets below 50 kHz) of the VCXO module or the crystal to clean the input clock. The output of PLL1 is used as
the clean input reference to PLL2 where it locks the integrated VCO. The loop bandwidth of PLL2 can be
optimized to clean the far-out phase noise (offsets above 50 kHz) where the integrated VCO outperforms the
VCXO module or crystal used in PLL1.
The LMK04000 family features dual redundant inputs, five differential outputs, and an optional default-clock upon
power up. The input block is equipped with loss of signal detection and automatic or manual selection of the
reference clock. Each clock output consists of a programmable divider, a phase synchronization circuit, a
programmable delay, and an LVDS, LVPECL, or LVCMOS output buffer. The default startup clock is available on
CLKout2 and it can be used to provide an initial clock for the field-programmable gate array (FPGA) or
microcontroller that programs the jitter cleaner during the system power up sequence.
