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 47.
1.3. Quality Standards
The quality of the IC will be ensured according to the ZMDI 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 V
unless otherwise stated.

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.
