(VREF = 2.5V, VCC3 = 3.13V to 3.47V, VCC5 = 4.5V to 5.25V, VAVDD = VOVDD = 1.7V to 1.9V, TA = 0NC to +70NC, VGND = 0V,
SHDN = 0, CWD = 1, SHDN = 0, LOON = 1, RIN = 200I, fRF = 5MHz, Source resistance RS = 200I, CI+, CI-, CQ+, CQ- pulled up to
+11V through four separate 0.1% 120I resistors). The rise/fall time of the LVDS clock driving LO+/LO- is required to be 0.5ns, refer-
ence noise less than 10nV/
√Hz from 1kHz to 20MHz (Note 10). Typical values are at VCC3 = 3.3V, VCC5 = 4.75V, VAVDD = VOVDD =
1.8V, TA = +25NC, unless otherwise noted.) (Note 3)
