1.
Valid for ambient operating temperature: TA = –20 °C to 85 °C; VCC = 2.5 V to 5.1 V; typical TA = 25 °C;
load capacitance = 20 pF, fMCLK = 26 MHz (except where noted).
2.
Total accuracy includes line and load regulation, temperature and process condition. It does not include load and line
transients.
3.
Simulated and determined via design and not 100% tested.
4.
Ripple voltage = 0.1 Vpp.
5.
Clock input voltage level should not exceed VTCXO voltage.
6.
The rise time is measured when clock edge transfers from 10% VCC to 90%VCC. The fall time is measured when clock
edge transfers from 90%VCC to 10%VCC. The output rise/fall time is guaranteed for all input slew rates.
7.
The quiescent current is measured when the enable pins are active, but with no input master clock signal (fMCLK = 0 Hz).
8.
The active current depends on the input master clock Vpp and frequency and the load condition. The typical test condition
is 26 MHz with 1.8 Vpp master clock input, CL = 20 pF.
9.
The test condition is VENH = 1.8 V and VENL = 0 V. When output enables simultaneously, there is no intentional skew in
design between the output clocks.
10. Guaranteed for all input clock slew rates.
