Hello, Please ask a question about TH72032 Datasheet
# Example questions:
➢ What resistor values (in kω) are recommended for rps to achieve output power steps 2 and 4?
➢ What is the typical start-up time (ton) for the th72032 transmitter when transitioning from standby to transmit mode?
➢ What are the spurious emission limits (in dbm) for frequencies below 1 ghz, with a resolution bandwidth of 100 khz, as defined by en 300 220-1?
1. Device Identification & General Information
️· Device: TH72032
️· Type: 868/915MHz ASK Transmitter
️· Revision: Data Sheet Rev. 008, June/07
️· Datasheet Page References: Pages 10, 11 of the datasheet.
️· Note: This is a data sheet extract, likely part of a larger document.
2. Start-up Parameters
️· Start-up Time (ton): 0.6 - 1 ms (from standby to transmit mode)
3. Frequency Stability
️· Frequency Stability vs. Supply Voltage (dfVCC): ±3 ppm
️· Frequency Stability vs. Temperature (dfTA):
- ±10 ppm (crystal at constant temperature - General Value)
- It appears the data sheet has different values for stability at different temperatures (125°C, 85°C, 25°C, 0°C, -20°C, -40°C), but the exact values are not provided in this extracted section. *Further datasheet reference needed*.
️· Frequency Stability vs. CRO Variation (dfCRO): ±20 ppm
4. Output Power Steps (Important for Transmitter Configuration)
️· RPS (Resistance Programming Steps) Values:
- Step 0: < 3 kΩ
- Step 1: 22 kΩ
- Step 2: 56 kΩ
- Step 3: 120 kΩ
- Step 4: Not Connected (Open Circuit)
️· Output Power Values (P1, P2, P3, P4):
- P0: -70 dBm
- P1: -13 to -111 dBm
- P2: -4 to -21 dBm
- P3: 1 to 3.51 dBm
- P4: 4 to 9.51 dBm
- *Note:* The output power values seem to depend on specific conditions and the datasheets tables are not completely clear.
5. Spurious Emissions
️· EN 300 220-1 Compliance:
- 47 MHz < f < 74 MHz: -54 dBm
- 87.5 MHz < f < 118 MHz: -54 dBm
- 174 MHz < f < 230 MHz: -36 dBm
- 470 MHz < f < 862 MHz: -36 dBm
- f > 1 GHz: -30 dBm
️· *Note:* "B" likely refers to bandwidth in the spurious emissions measurements, but the values aren't specified.
6. Other Notes/Ambiguities
️· Temperature Range: The datasheet refers to different temperature ratings (125°C, 85°C, 25°C, 0°C, -20°C, -40°C), suggesting different operating conditions and possibly different performance characteristics.
️· Output Matching Network: It's stated that the output power values are dependent on a tuned output matching network for a 5V supply. This implies that the values provided are valid only under those conditions. A different supply voltage or output configuration could alter the power levels.
️· Unclear Measurements: Some measurements lack specifics (bandwidths, precise test conditions).
️· Table Disconnect: Some tables on page 85C are incomplete, potentially showing incorrect data
To fully understand and utilize this information, you would likely need the complete TH72032 datasheet, as it references information not included in this extract. Specific details regarding the measurement conditions, test setups, and related tables are essential for accurate design and implementation.
