1 DC-Parameter:
VUINmin = VUOUTmin + VDROPmax
VUINmax = VUOUTmax + VDROPmin
Below VUINmin the power supply block may not be able to provide the specified output currents at
UOUT and U5R.
2 Outside of these limits the send current shape and send current amplitude cannot be guaranteed.

Crystal frequency
8.000/16.000 MHz
4 The IC automatically detects whether the crystal frequency is 8.000MHz or 16.000MHz and controls the
internal clock circuit accordingly. The frequency detection is locked as soon as one AS-i telegram was
correctly received at any input channel. It can be reset by Power On Reset only.
Note: In Slave Mode the locking occurs if a Master Call was received. In Master-/ Repeater-/Monitor
Mode a Master Call or a Slave Response that was received on any input channel, triggers the frequency
locking.
The ASI4U supports an integrated clock watchdog. If no crystal or clock oscillation is recognized for 150µs the
IC generates a RESET event until clock oscillation is available.
More detailed oscillator pin definitions can be found in chapter 3.10 on page 41.
1.3 Quality Standards
The quality of the IC will be ensured according to the ZMD quality standards. Functional device parameters are
valid for device operating conditions specified in chapter 1.2. Production device tests are performed within the
recommended ranges of VASIP - VASIN, VIN - V0V, θamb = + 25°C (+ 85°C and - 25°C on sample base only) unless
otherwise stated.
