In our testing of the same production 6G SAS HBA design with both the DSC1122 Silicon MEMS oscillator and a 3rd overtone crystal oscillator, we found that the use of the DSC1122 resulted in equivalent system performance with a bit lower measured transmitter random jitter and total jitter," said Mike Engbretson, Chief Technology Engineer of Granite River Labs.
These solutions provide a strong alternative to expensive and inflexible SAW oscillators and overtone crystal oscillators.
Epson's HFF crystal technology is more reliable than legacy 3rd overtone crystals which are commonly used for these frequencies.
