Device Configuration 1

For Vcc = 3.3 V (Nominal) 1 unit was characterized from 83MeV down to 2.76MeV. 20Ne was used to obtain LETEFF of 2.76MeV×cm2/mg. 40Ar was used to obtain LETEFF of 7.5MeV×cm2/mg. 59Co was used to obtain LETEFF of 16MeV×cm2/mg. 84Kr was used to obtain LETEFF of 27MeV×cm2/mg. 109Ag was used to obtain LETEFF of 45MeV×cm2/mg. 129Xe was used to obtain LETEFF of 56MeV×cm2/mg. 169Tm was used to obtain LETEFF of 70MeV×cm2/mg. 197Au was used to obtain LETEFF of 83MeV×cm2/mg. In this device configuration, the output frequency for RFOUT_AP = 206.25MHz and RFOUT_BP = 68.75MHz. RFOUT_AP output is the main divided down low noise clock and RFOUT_BP is SYSREF. Both outputs are characterized below. The Tektronix MSO68B oscilloscope was used to monitor RFOUT_AP and RFOUT_BP signals of the LMX2624-SP with the respective signal triggering off a 1% window. A trigger of 4.8ns was used for RFOUT_AP outputs in this section. Also, a trigger of 14.5 ns was used for RFOUT_BP outputs in this section. Table 7-2 summarizes the events seen in this mode on RFOUT_AP Output. Table 7-3 summarizes the events seen in this mode on RFOUT_BP.
