Table 2-7 lists the non-RF system level characteristics for the EM35x.
2.7.1
Table 2-8 lists the key parameters of the integrated IEEE 802.15.4-2003 receiver on the EM35x.
Note: Receive measurements were collected with Ember’s EM35x Ceramic Balun Reference Design (Version
A0) at 2440 MHz. The Typical number indicates one standard deviation above the mean, measured at room
temperature (25°C). The Min and Max numbers were measured over process corners at room temperature
