TR8100-021307
LOSyn Bit 7 - This bit is only used in product testing. It should always be
set to 0 for normal operation. The power-on default value of this bit is 0.
LOSyn Bits 6, 5, 4, 3, 2, 1, 0 -These bits have no function in the TR8100
and can be written as either a logic 1 or a logic 0.
Note that data to/from the configuration registers is clocked in/out most
significant bit first (MSB). See the Control Register Read/Write Detail and
Control Register Read/Write Timing Drawings for additional details.
Receiver Turn-On Timing
The maximum time t
PR
required for the receive function to become
operational at turn-on is influenced by two factors. All receiver circuitry will
be operational 1 ms after the supply voltage reaches 2.2 Vdc. The
BBOUT-CMPIN coupling-capacitor is then DC stabilized in 4 time con-
stants (4*t
BBC
). The total turn-on time to stable receiver operation for a
10 ms power supply rise time is:
t
PR
=15 ms +4*t
BBC
Receiver Wake-Up Timing
The maximum transition time
tSR
from the sleep mode to the receive
mode is 4*t
BBC
, where t
BBC
is the BBOUT-CMPIN coupling-capacitor
time constant. When the operating temperature is limited to 60°C,
the time required to switch from sleep to receive is dramatically less
for short sleep times, as less charge leaks away from the BBOUT-CMPIN
coupling capacitor.
AGC Timing
The maximum AGC engage time t
AGC
is 5 μs after the reception of a
-30 dBm RF signal with a 1 μs envelope rise time.
Peak Detector Timing
The Peak Detector attack time constant is set by the value of the capacitor
at the PKDET pin. The attack time t
PKA
=C
PKD
/4167, where
t
PKA
is in μs and C
PKD
is in pF. The Peak Detector decay time constant
t
PKD
= 1000*t
PKA
