IDT™ / ICS™ QUADRACLOCK QUADRATURE DELAY BUFFER
ICS672-01/02
QUADRACLOCK QUADRATURE DELAY BUFFER
VDD = VDDIO = 3.3 V, Ambient Temperature 0 to +70 C, unless stated otherwise
Note 1: With ICLK = 20 MHz, FBCLK to FBIN, all outputs at 40 MHz.
Note 2: With ICLK = 66.5 MHz, FBCLK to FBIN, all outputs at 133 MHz.
Note 3: Value depends on multiplier. Must also meet output clock frequency.
Note 4: With CLK0CLK270 equally loaded, and output frequency > 60 MHz.
Note 5: Rising edge of ICLK compared with rising edge of CLk0, with FBCLK connected to FBIN, 15 pF load on
CLK0, and CLK0 > 60 MHz.
Note 6: Commercial grade.
Note 7: Industrial grade.
