Unit Note fc Crystal frequency 8.000/16.000 MHz 4 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 6. 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 VASIP - VASIN, VIN - V0V, amb = + 25°C (+ 85°C and - 25°C/[-40°C ASI4U-F] on sample base only) unless otherwise stated. |
