Frequently Asked Questions
What output frequency and signal standard does the LMK61A2-100M00SIA provide for FPGA clocking applications?
The LMK61A2-100M00SIA outputs a 100 MHz clock in LVDS differential format, with a maximum supported rate of 312.5 MHz in the broader LMK61A2 family. The LVDS standard delivers low-noise, balanced differential signaling that is well-suited for clocking FPGAs, SerDes lanes, and high-speed ADCs requiring clean 100 MHz reference edges.
How does the ±50 ppm frequency stability of the LMK61A2-100M00SIA compare to standard crystal oscillators in timing-critical designs?
At ±50 ppm, the LMK61A2-100M00SIA matches the stability of typical industrial-grade crystal oscillators. Combined with its PLL-based architecture and ultra-low phase jitter, it reduces timing uncertainty across temperature and aging, making it preferable to discrete XO solutions in Ethernet, PCIe, and data converter clock networks where cumulative jitter budget is tight.
What is the integrated PLL architecture of the LMK61A2-100M00SIA and how does it simplify PCB layout?
The LMK61A2-100M00SIA integrates a complete PLL-based clock driver internally, eliminating the need for external loop filter resistors and capacitors that standard VCO-based clock circuits require. This integration reduces component count by at least 5 to 8 passive parts, shrinks PCB area, and lowers susceptibility to layout-induced noise coupling on high-frequency clock planes.
Which communication interface standards benefit most from the LMK61A2-100M00SIA's ultra-low jitter output?
The LMK61A2-100M00SIA directly supports JESD204B, PCIe Gen 2, Gigabit Ethernet, and LVDS-clocked ADC interfaces that specify sub-200 fs RMS jitter budgets. At 100 MHz with LVDS differential output, the oscillator provides a clean, stable reference that keeps bit-error rates below 10E-12 in high-speed serial links operating at multi-gigabit data rates.
