CY2305C CY2309C 3.3V Zero Delay Clock Buffer Features ■ ■ ■ ■ ■ ■ ■ ■ 10 MHz to 100-133 MHz operating range Zero input and output propagation delay Multiple low skew outputs One input drives five outputs (CY2305C) One input drives nine outputs, grouped as 4 + 4 + 1 (CY2309C) 50 ps typical cycle-cycle jitter (15 pF, 66 MHz) Test Mode to bypass phase locked loop (PLL) (CY2309C) only, see “Select Input Decoding for CY2309C” on page 3 Available in space saving 16-pin 150 Mil SOIC or 4.4 mm TSSOP packages (CY2309C), and 8-pin, 150 Mil SOIC package (CY2305C) 3.3V operation Commercial, Industrial and Automotive-A flows available skew clocks. The -1H versions of each device operate 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. The CY2309C has two banks of four outputs each that are controlled by the select inputs as shown in the “Select Input Decoding for CY2309C” on page 3. If all output clocks are not required, BankB is three-stated. The input clock is directly applied to the outputs by the select inputs for chip and system testing purposes. The CY2305C and CY2309C 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. This results in less than 12.0 μA of current draw for commercial temperature devices and 25.0 μA for industrial and automotive-A temperature parts. The CY2309C PLL shuts down in one additional case as shown in the “Select Input Decoding for CY2309C” on page 3. In the special case when S2:S1 is 1:0, the PLL is bypassed and REF is output from DC to the maximum allowable frequency. The part behaves as a non-zero delay buffer in this mode and the outputs are not three-stated. The CY2305C or CY2309C is available in two or three different configurations as shown in the “Ordering Information” on page 9. The CY2305C-1 or CY2309C-1 is the base part. The CY2305-1H or CY2309-1H is the high drive version of the -1. Its rise and fall times are much faster than the -1. ■ ■ Functional Description The CY2305C and CY2309C are die replacement parts for CY2305 and CY2309. The CY2309C is a low cost 3.3V zero delay buffer designed to distribute high speed clocks and is available in a 16-pin SOIC or TSSOP package. The CY2305C is an 8-pin version of the CY2309C.

Since the CLKOUT pin is the internal feedback to the PLL, its relative loading can adjust the input or output delay. For applications requiring zero input or output delay, all outputs including CLKOUT are equally loaded. Even if CLKOUT is not used, it must have a capacitive load equal to that on other outputs for obtaining zero input or output delay. For zero output or output skew, all outputs are loaded equally. For further information refer to the application note entitled “CY2305 and CY2309 as PCI and SDRAM Buffers”. Notes 3. Weak pull ups on these inputs. 4. This output is driven and has an internal feedback for the PLL. The load on this output is adjusted to change the skew between the reference and output.
