CY2305, CY2309 Low Cost 3.3-V Zero Delay Buffer Features Functional Description ■ Not recommended for new designs. The CY2305C and CY2309C are form, fit, function compatible devices with improved specifications. ■ 10 MHz to 100/133 MHz operating range, compatible with CPU and PCI bus frequencies ■ Zero input-output propagation delay ■ 60-ps typical cycle-to-cycle jitter (high drive) The CY2309 is a low-cost 3.3-V zero delay buffer designed to distribute high speed clocks and is available in a 16-pin SOIC or TSSOP package. The CY2305 is an 8-pin version of the CY2309. It accepts one reference input, and drives out five low skew clocks. The -1H versions of each device operate at up to 100-/133 MHz frequencies, and have higher drive than the -1 devices. All parts have on-chip PLLs which lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad. ■ Multiple low skew outputs ❐ 85 ps typical output-to-output skew ❐ One input drives five outputs (CY2305) ❐ One input drives nine outputs, grouped as 4 + 4 + 1 (CY2309) ■ Compatible with Pentium-based systems ■ Test Mode to bypass phase-locked loop (PLL) (CY2309) ■ Packages: ❐ 8-pin, 150-mil SOIC package (CY2305) ❐ 16-pin 150-mil SOIC or 4.4-mm TSSOP (CY2309) ■ 3.3-V operation ■ Commercial and industrial temperature ranges The CY2309 has two banks of four outputs each, which can be controlled by the select inputs as shown in “Select Input Decoding for CY2309” on page 4. If all output clocks are not required, BankB can be three-stated. The select inputs also allow the input clock to be directly applied to the outputs for chip and system testing purposes. The CY2305 and CY2309 PLLs enter a power-down mode 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 in less than 25.0 μA current draw for these parts. The CY2309 PLL shuts down in one additional case as shown in “Select Input Decoding for CY2309” on page 4. Multiple CY2305 and CY2309 devices can accept the same input clock and distribute it. In this case, the skew between the outputs of two devices is guaranteed to be less than 700 ps. The CY2305/CY2309 is available in two or three different configurations, as shown in “Ordering Information for CY2305” on page 13. The CY2305-1/CY2309-1 is the base part. The CY2305-1H/ CY2309-1H is the high-drive version of the -1, and its rise and fall times are much faster than the -1.

REF. Input to CLKA/CLKB Delay vs. Loading Difference between CLKOUT and CLKA/CLKB Pins Zero Delay and Skew Control All outputs must be uniformly loaded to achieve zero delay between the input and output. Because the CLKOUT pin is the internal feedback to the PLL, its relative loading can adjust the input-output delay. This is shown in the above graph. For applications requiring zero input-output delay, all outputs, including CLKOUT, must be equally loaded. Even if CLKOUT is not used, it must have a capacitive load, equal to that on other outputs, for obtaining zero input-output delay. If input to output delay adjustments are required, use Figure 3 to calculate loading differences between the CLKOUT pin and other outputs. For zero output-output skew, be sure to load all outputs equally. For further information, refer to the application note titled “CY2305 and CY2309 as PCI and SDRAM Buffers.” Notes 4. Weak pull down on all outputs 5. This output is driven and has an internal feedback for the PLL. The load on this output can be adjusted to change the skew between the reference and output.
