TR8000-10182007

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

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-

10 ms power supply rise time is:

Receiver Wake-Up Timing

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

-30 dBm RF signal with a 1 µsenvelope rise time.

Peak Detector Timing

The Peak Detector attack time constant is set by the value of the capacitor
