LIN Bus Bit Time
Calculate nominal LIN bit duration as 1e6 / bit rate in microseconds, for the documented 1–20 kbit/s range. Frame overhead and clock tolerance are excluded.
Description
LIN bit duration is the reciprocal of nominal bit rate.
LIN bit duration is the reciprocal of nominal bit rate. Frame duration also includes framing and protocol overhead.1
Calculate nominal LIN bit duration as 1e6 / bit rate in microseconds, for the documented 1–20 kbit/s range. Frame overhead and clock tolerance are excluded.
When to use LIN Bus Bit Time
Use this tool to calculate nominal LIN bit duration as 1e6 / bit rate in microseconds, for the documented 1–20 kbit/s range. Frame overhead and clock tolerance are excluded.
Prepare comparable frequency measurements or the nominal bus bit rate in the units requested.
How to use LIN Bus Bit Time and understand its results
- Prepare comparable frequency measurements or the nominal bus bit rate in the units requested.
- Enter bitRateBps using the field table and calculation rules, then run the tool.
- Read bitTimeMicroseconds. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| bitRateBps | Nominal LIN bit rate. (bit/s) | number; minimum: 1000; maximum: 20000 | Required |
Enter rate 1000–20000 bit/s; return nominal microseconds per bit.
bitTimeµs=1,000,000/bitRateBps Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| bitTimeMicroseconds | Nominal duration of one bit. (us) | number; strictly above: 0 |

}Limitations and assumptions
No frame overhead, clock tolerance or bus measurement is modeled.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Crystal Aging Frequency Change: Calculate signed measured frequency change in ppm relative to the initial frequency: 1e6 × (aged − initial) / initial. Measurements must use the same conditions; this does not predict an aging curve. For a complementary task, use Escapement Impulse Rate: Compare detent, duplex, and natural-escapement impulse rates from the balance beat rate without conflating beat and full oscillation.
