Si4455

1.1. Definition of Test Conditions

Production Test Conditions:

ï®ï TA = +25 Â°C

ï®ï VDD = +3.3 VDC

ï®ï Sensitivity measured at 434 MHz using a PN15 modulated input signal and with packet handler mode

enabled.

ï®ï External reference signal (XIN) = 1.0 VPP at 30 MHz, centered around 0.8 VDC

ï®ï RF input and output levels can typically be achieved at the antenna port after filtering components.

Qualification Test Conditions:

ï®ï TA = â40 to +85 Â°C (typical = 25 Â°C)

ï®ï VDD = +1.8 to +3.6 VDC (typical = 3.3 VDC)

ï®ï Use TX/RX Split Antenna reference design or production test schematic

ï®ï RF input and output levels can typically be achieved at the antenna port after filtering components.
