AMIS-53000
Frequency Agile Transceiver
Data Sheet
The Sniff Mode of operation puts the AMIS-53000 receiver into a cyclic mode of sleeping and periodically waking to check for received
signal energy. When energy is detected the receiver is placed in receive mode and the AMIS-53000 attempts to recover data. The
receiver in Sniff Mode can be configured to check for a valid ID. The failure to receive a valid ID will cause the receiver to go back to
sleep.
The AMIS-53000 receiver average supply current can be estimated as:
Where,
is receiver current consumption in continuous receive mode, equal to or less than 12mA;
is receiver current consumption in sleep mode, equal to or less than 2uA;
is programmable receiver energy scan impulse on time (sniff time), approximately equal to 130
μ
s minimum;
is programmable receiver off time period length between receiver energy scan impulses (sniff mode interval).
Setup re
Code Dwell Time
- Once RF energy has been detected the receiver can determine if the message has the unique ID for that
receiver. The time interval for looking for this ID must be set. (See Chip ID Dwell Timer)
Threshold
- The number of times a wake up is received can be monitored for false wake ups and the energy threshold
adjusted to account for the noise level.
he Sniff config register is used to set additional options for the operation of the part during a Sniff cycle, beyond those set in the RX
config re
SNIFF_FILTER:
Setting for the energy detection filter. This allows for different settings of the AM data filter between Sniff and
receive. The energy dwell timer needs to be extended long enough to allow for this filter to settle during the Sniff cycle.
Auto-Threshold Count Value:
Number of Sniff cycles used to determine whether to raise or lower the energy threshold for
sniff. Any value other than 0x00 in this register will enable the auto-threshold function.
Multi Channel:
This bit is used in MICS mode of operation to enable the AMIS-53000 to scan the nine pre-defined MICS
channels programmed into the AMIS-53000.
Sniff Interval Resolution:
Determines the clock for the Sniff interval timer.
gisters descriptions:
Sniff Config
-This sets the options in the Sniff Mode.
Sniff Interval
- Set the time interval between receiver wakeups in the Sniff Mode.
Energy Threshold
- The threshold for detecting the incoming RF energy must be set (see Section 6.5.1.2).
Energy Dwell Time
- Set the time interval that the receiver will remain active looking for RF energy detection.
