Functional Description

The CY2308 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 that locks to an input clock presented on the REF pin. The PLL feedback is driven into the FBK pin and obtained from one of the outputs. The input-to-output skew is less than 350 ps and output-to-output skew is less than 200 ps.

Logic Block Diagram

The CY2308 has two banks of four outputs each that is controlled by the select inputs as shown in the table Select Input Decoding on page If all output clocks are not required, Bank B is three-stated. The input clock is directly applied to the output for chip and system testing purposes by the select inputs.

The CY2308 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 the table Select Input Decoding on page

Multiple CY2308 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 CY2308 is available in five different configurations as shown in the table Available CY2308 Configurations 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 the user to obtain 2X and 1X frequencies on each output bank. The exact configuration and output frequencies depend on the output that drives the feedback pin. The enables the user to obtain 4X and 2X frequencies on the outputs.

The enables the user to obtain 2X clocks on all outputs. Thus, the part is extremely versatile and is used in a variety of applications.

The is a high drive version with REF/2 on both banks.
