• Manufacturer Part Number: stcd1020
• Description: Multi-channel Clock Distribution Circuit
• Manufacturer: STMicroelectronics

Table 7.
1. Valid for ambient operating temperature: T
2.
3. Simulated and determined via design and NOT 100% tested.
4. The quiescent current is measured when the enable pins are active, but without input master clock signal (fmclk = 0 Hz).
5. The active current is dependent on the master clock input Vpp and frequency and the capacitive load condition. The
6. The rise time is measured when clock edge transfers from 10% V
7. Other test results are under test condition V
8. Guaranteed with the supply noise of 30 μ Vrms from 300 Hz to 50 kHz.
