CY2308
3.3V Zero Delay Buffer
Features

Zero input-output propagation delay, adjustable by capacitive load on FBK input Multiple configurations, see "Available CY2308 Configurations" on page 3 Multiple low skew outputs Two banks of four outputs, three-stateable by two select inputs 10 MHz to 133 MHz operating range 75 ps typical cycle-to-cycle jitter (15 pF, 66 MHz) Space saving 16-pin 150 mil SOIC package or 16-pin TSSOP 3.3V operation Industrial Temperature available
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 2". 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 A of current draw. The PLL shuts down in two additional cases as shown in the table "Select Input Decoding" on page 2. 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 3. The CY2308-1 is the base part where the output frequencies equal the reference if there is no counter in the feedback path. The CY2308-1H is the high drive version of the -1 and rise and fall times on this device are much faster. The CY2308-2 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 CY2308-3 enables the user to obtain 4X and 2X frequencies on the outputs. The CY2308-4 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 CY2308-5H is a high drive version with REF/2 on both banks.
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.

Zero Delay and Skew Control
Figure 2. REF. Input to CLKA/CLKB Delay Versus Difference in Loading between FBK pin and CLKA/CLKB Pins
To close the feedback loop of the CY2308, the FBK pin is driven from any of the eight available output pins. The output driving the FBK pin drives a total load of 7 pF plus any additional load that it drives. The relative loading of this output to the remaining outputs adjusts the input-output delay. This is shown in the Figure 2. For applications requiring zero input-output delay, all outputs including the one providing feedback is equally loaded.
If input-output delay adjustments are required, use the Zero Delay and Skew Control graph to calculate loading differences between the feedback output and remaining outputs. For zero output-output skew, outputs are loaded equally. For further information on using CY2308, refer to the application note "CY2308: Zero Delay Buffer."
Note 5. Output phase is indeterminant (0 or 180 from input clock). If phase integrity is required, use the CY2308-2.
