LMK04906BEVAL
개요
The LMK04906 is the industry's highest performance clock conditioner with superior clock jitter cleaning, generation, and distribution with advanced features to meet next generation system requirements. The dual loop PLLatinum™ architecture enables 111 fs rms jitter (12 kHz to 20 MHz) using a low noise VCXO module or sub-200 fs rms jitter (12 kHz to 20 MHz) using a low cost external crystal and varactor diode.
The dual loop 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 the integrated crystal oscillator with an external tunable crystal and 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 tunable 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 tunable crystal used in PLL1.

TICS Pro 1.7.10.2 Release Notes
TICS Pro 1.7.10.2 Software Manifest
출시 정보
v1.7.10.2 contains bug fixes and improvements to TICS Pro core binary and many devices.
Improvements
- See release notes for complete list of updates
- Updated LMK05318B, CDCE6214-Q1, LMK5Bxxxxx, LMK5CxxxxxA, and PCIe Report Generator
Bugfixes
- See release notes for complete list of bug fixes
- Fix Raw Registers page bug that overwrote addresses
- Fix Burst Mode race condition
- Fixed LMK05318B and LMK5Bxxxxx/LMK5CxxxxxA desynchronization and EEPROM script issues
Known Issues
- LMK5B and LMK5C family - In some cases, "Assign Selected VCO Settings to Device" and "Apply Output Clock Settings to Device" may need to be pressed twice for certain cascaded configurations to display correctly
- LMK05318 - In some cases, it is necessary to press "Calculate Frequency Plan" twice for correct VCO2 frequency. This issue is resolved in LMK05318B GUI.
- User Controls page can sometimes become desynchronized from Raw Registers and other pages. Refer to Raw Registers or other pages for correct values. Saving/Loading and Import/Export of register data is unaffected, and register data will still be written to and read from connected devices correctly.
