• Manufacturer Part Number: ics581
• Description: Zero Delay Glitch-free Clock Multiplexer
• Manufacturer: Integrated Device Technology

AC Electrical Characteristics
IDT™ / ICS™ ZERO DELAY GLITCH-FREE CLOCK MULTIPLEXER
ICS581-01/02
ZERO DELAY GLITCH-FREE CLOCK MULTIPLEXER
Unless stated otherwise, VDD = 3.3 V ±5%, Ambient Temperature -40 to +85° C
Note 1: Assumes clocks with same rise times, measured at VDD/2.
Note 2: Assumes identically loaded outputs with identical rise times, measured at VDD/2. The maximum skew between any two
clocks is 250 ps not 500 ps.
Note 3: Time taken for output to lock to new clock when mux selection changed from INA to INB.
Note 4. With 50 MHz on INA and 150 MHz on INB.
Note 5: With 100 MHz on both INA and INB, 180° out of phase.
