Jitter_typ

...

typical phase jitter at Tj=25°C in ° (1Sigma)

Jitter_max ...

maximum phase jitter at Tj=175°C in ° (3Sigma)

∂

∂ϕ

...

inverse of the magnetic slope of the edge in °/T

Bneff_typ

...

typical value of Bdiff in T

σ-value at Tj=25°C)

Bneff_max

...

maximum value of Bdiff in T

σ-value at Tj=175°C)

Example:

Assumption:

n = 4500 min

-1

td = 14 µs

∆t

d = ±3 µs

∂

∂B

= 3 mT/°

Bneff_typ = ±40 µT (1

σ-value at Tj=25°C)

Bneff_max = ±210 µT (3

σ-value at Tj=175°C)

Calculation:

= 0.378°

...

systematic phase error

∆ϕ

= ±0.081°

...

stochastic phase error due to delay time variation

Jitter_typ = ±0.013°

...

typical phase jitter (1

σ-value at Tj=25°C)

Jitter_max = ±0.07°

...

maximum phase jitter (3

σ-value at Tj=175°C)
