DATASHEET ICS672-01/02 QUADRACLOCK QUADRATURE DELAY BUFFER Description Features The ICS672-01/02 are zero delay buffers that generate four output clocks whose phases are spaced at 90° intervals. Based on IDT’s proprietary low jitter Phase-Locked Loop (PLL) techniques, each device provides five low-skew outputs, with clock rates up to 84 MHz for the ICS672-01 and up to 135 MHz for the ICS672-02. By providing outputs delayed one quarter clock cycle, the device is useful for systems requiring early or late clocks. The ICS672-01/02 include multiplier selections of x0.5, x1, x2, x3, x4, x5, or x6. They also offer a mode to power-down all internal circuitry and tri-state the outputs. In normal operation, output clock FBCLK is tied to the FBIN pin. • Packaged in 16-pin SOIC • Pb (lead) free package, RoHS compliant • Input clock range from 5 MHz to 150 MHz (depends on multiplier) • Clock outputs from up to 84 MHz (ICS672-01) and up to 135 MHz (ICS672-02) • Zero input-output delay • Integrated x0.5, x1, x2, x3, x4, x5, or x6 selections • Four accurate ( 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.
