TDA523x
Specifications
Unless explicitly otherwise noted, the following test conditions apply to the given
specification values in Tables 7..12:
TDA5230:
* Hardware: Testboard TDA523x V2.1
* Single-Ended Matching for 433.92 MHz
* Receive Frequency 433.92 MHz; Lo-Side LO-Injection
* Reference-Clock: XTAL=13.225625 MHz; RF-PLL: R=2, S=0
TDA5231:
* Hardware: Testboard TDA523x V2.1
* Single-Ended Matching for 315.00 MHz
* Receive Frequency 315.00MHz; Hi-Side LO-Injection
* Reference-Clock: XTAL=15.2671875 MHz; RF-PLL: R=2, S=0
TDA5230 and TDA5231:
* IF-Gain: Attenuation set to minimum
* IF-Filter: Center=10.7MHz; BW=280kHz; Connected between IF-OUT and LIM-IN+
* Received-Signal at zero Offset to IF Center Frequency
* RSSI trimmed
* FSK-Demodulator Pre-filter BW +/-250
* No SPI-traffic during telegram reception, CLKOUT disabled
* Specification values are in respect to Manchester-coded Reference Protocol
(11 Bits '0' ,1 Bit ’1' , PRBS5 (31 Bit), 1 Bit 'M') according to Figure 37
* DRE ... Data-Rate Error of received telegram vs. adjusted Data-Rate
* DC ... Duty-Cycle
(duration of first chip of manchester-coded bit in respect to duration of complete bit according to Figure 37)
* MER ... Message Error Rate
[MER = 1 - (number_of_correctly_received_messages / number_of_transmitted messages)]
* FAR ... False Alarm Rate
[FAR = number_of_mistakenly_wake_ups / number_of_periods_searching_for_data_on_channel]
* MMR ... Missed Message Rate
[MMR = number_of_mistakenly_missed_wake_up_patterns /
number_of_periods_with_wake_up_pattern_transmitted_and_searching_for_wake_up_pattern]
