Pin ENABLE
Via the pin ENABLE the operating mode of the receiver can be selected (see Figure 5-1 and Fig-
ure 5-2).
If the pin ENABLE is held to Low, the receiver remains in sleep mode. All circuits for signal pro-
cessing are disabled and only the XTO is running in that case. The current consumption is
I
S = ISoff in that case. During the sleep mode the receiver is not sensitive to a transmitter signal.
To activate the receiver, the pin ENABLE must be held to High. During the start-up period,
T
Startup, all signal processing circuits are enabled and settled. The duration of the start-up period
depends on the selected baud-rate range (BR_Range).
After the start-up period, all circuits are in a stable condition and the receiver is in the receiving
mode.
In receiving mode, the internal data signal (Dem_out) is switched to pin DATA. To avoid incor-
rect timing at the begin of the data stream, the begin is synchronized to a falling edge of the
incoming data signal. The receiver stays in the receiving mode until it is switched back to sleep
mode via pin ENABLE.
During start-up and receiving mode, the current consumption is I
S = ISon.
