com ICS527-01 Clock Slicer™ User Configurable Zero Delay Buffer Description The ICS527-01 Clock Slicer™ is the most flexible way to generate an output clock from an input clock with zero skew.
The user can easily configure the device to produce nearly any output clock that is multiplied or divided from the input clock.
The part supports non-integer multiplications and divisions.
A SYNC pulse indicates the rising clock edges that are aligned with zero skew.
Using Phase-Locked Loop (PLL) techniques, the device accepts an input clock up to 200 MHz and produces an output clock up to 160 MHz.
The ICS527-01 aligns rising edges on ICLK and FBIN at a ratio determined by the reference and feedback dividers.
For configurable clocks that do not require zero delay, use the ICS525.
Features • Packaged as 28 pin SSOP (150 mil body) • Synchronizes fractional clocks rising edges • User determines the output frequency - no software needed • Slices frequency or period • SYNC pulse output indicates aligned edges • Input clock frequency of 600 kHz - 200 MHz • Output clock frequencies up to 160 MHz • Very low jitter • Duty cycle of 45/55 up to 160 MHz • Operating voltage of 3.
3 V (±10%) • Pin selectable double drive strength • Multiple outputs available when combined with Buffalo clock drivers • Zero input to output skew • Industrial temperature version available • Advanced, low power CMOS process S1:S0 2 PDTS CLK1 PLL PDTS ÷2 SYNC 1 0 Block Diagram R6:R0 7 ICLK Reference Divide Feedback Divide 7 2XDRIVE FBIN CLK2 DIV2 PDTS OECLK2 F6:F0 External feedback from CLK1 or CLK2 (not both).
