DAC INPUT CLOCK OVERCLOCKING SPECIFICATIONS
VDD25_DAC = 2.5 V, VDD12A = VDD12_CLK = 1.2 V, VNEG_N1P2 = −1.2 V, DVDD = 1.2 V, IOVDD = 2.5 V, VDD_1P2 =
DVDD_1P2 = PLL_LDO_VDD12 = 1.2 V, SYNC_VDD_3P3 = 3.3 V, IOUTFS = 40 mA, TA = −40°C to +85°C, unless otherwise noted.
Maximum guaranteed speed using the temperature and voltage conditions as shown in Table 2, where VDDx is VDD12_CLK, DVDD,
VDD_1P2, DVDD_1P2, and PLL_LDO_VDD12. Any DAC clock speed over 5.1 GSPS requires a maximum junction temperature that does not
exceed 105°C to avoid damage to the device. See Table 10 for details on maximum junction temperature permitted for certain clock
speeds.
