CY23S09, CY23S05 Low Cost 3.3 V Spread Aware Zero Delay Buffer All parts have on-chip PLLs that lock to an input clock on the REF Features pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad. 10 MHz to 100 MHz and 133 MHz operating range, compatible with CPU and PCI bus frequencies The CY23S09 has two bans of four outputs each, which can be controlled by the select inputs as shown in the Select Input Zero input-output propagation delay Decoding table on Select Input Decoding for CY23S09 on page Multiple low skew outputs 4. If all output clocks are not required, Bank B can be three-stated. The select inputs also allow the input clock to be Output-output skew less than 250 ps directly applied to the outputs for chip and system testing Device-device skew less than 700 ps purposes. One input drives five outputs (CY23S05) One input drives nine outputs, grouped as 4 + 4 + 1 The CY23S09 and CY23S05 PLLs enter a power down mode (CY23S09) when there are no rising edges on the REF input. In this state, the outputs are three-stated and the PLL is turned off, resulting Less than 200 ps Cycle-to-cycle jitter in less than 12.0 A of current draw (for commercial temperature Test mode to bypass PLL (CY23S09 only, see Select Input devices) and 25.0 A (for industrial temperature devices). The Decoding for CY23S09 on page 4) CY23S09 PLL shuts down in one additional case, as shown in the Select Input Decoding for CY23S09 on page 4. Available in space saving 16-pin, 150-mil SOIC, 4.4 mm Multiple CY23S09 and CY23S05 devices can accept the same TSSOP (CY23S09) or 8-pin, 150-mil input clock and distribute it. In this case, the skew between the SOIC package (CY23S05) outputs of two devices is guaranteed to be less than 700 ps. 3.3 V operation, advanced 0.65 CMOS technology All outputs have less than 200 ps of cycle-to-cycle jitter. The input Spread Aware to output propagation delay on both devices is guaranteed to be less than 350 ps the output to output skew is guaranteed to be Functional Description less than 250 ps. The CY23S05 and CY23S09 is available in two different config- The CY23S09 is a low cost 3.3 V zero delay buffer designed to urations, as shown in the Ordering Information on page 8. The distribute high speed clocks and is available in a 16-pin SOIC CY23S05-1 and CY23S09-1 is the base part. The CY23S05-1H package. The CY23S05 is an 8-pin version of the CY23S09. It and CY23S09-1H is the high drive version of the -1, and its rise accepts one reference input, and drives out five low skew clocks. and fall times are much faster than -1. The -1H versions of each device operate at up to 100 and For a complete list of related resources, click here. 133 MHz frequencies and have higher drive than the -1 devices.
