CY23S08 3.3V Zero Delay Buffer 3.3V Zero Delay Buffer • Zero Input Output Propagation Delay, adjustable by Capacitive Load on FBK input • Multiple configurations see Table 3 on page 4 • Multiple Low-skew Outputs 45 ps Typical Output-output skew Two banks of four Outputs, three-stateable by two select Inputs • 10 MHz to 140 MHz Operating Range • 65 ps Typical Cycle-to-cycle Jitter • Advanced um CMOS Technology • Space saving 16-pin, SOIC and TSSOP Packages • 3.3V Operation • Spread Aware Functional Description The CY23S08 is a 3.3V zero delay buffer designed to distribute high speed clocks in PC, workstation, datacom, telecom, and other high performance applications. The part has an on-chip PLL which locks to an input clock presented on the REF pin. The PLL feedback must be driven into the FBK pin, and obtained from one of the outputs. The input-to-output propagation delay is less than 350 ps, and output-to-output skew is less than 250 ps. The CY23S08 has two banks of four outputs each, which can be controlled by the Select inputs as shown in Table 2 on page If all output clocks are not required, Bank B can be three-stated. The select inputs also enable the input clock to be directly applied to the output for chip and system testing purposes. The CY23S08 PLL enters a power down state when there are no rising edges on the REF input. In this mode, all outputs are three-stated and the PLL is turned off, resulting in less than 50 uA of current draw. The PLL shuts down in two additional cases as shown in Table 2 on page Multiple CY23S08 devices accept the same input clock and distribute it in a system. In this case, the skew between the outputs of two devices is less than 700 ps. The CY23S08 is available in five different configurations, as shown in Table 3 on page The is the base part, where the output frequencies equal the reference if there is no counter in the feedback path. The is the high drive version of the and rise and fall times on this device are much faster. The enables you to obtain 2X and 1X frequencies on each output bank. The exact configuration and output frequencies depends on which output drives the feedback pin. The is the high drive version of the and rise and fall times on this device are much faster. The enables you to obtain 2X clocks on all outputs. Thus, the part is versatile, and can be used in a variety of applications.
