CY2308SC-1T

Clock Buffers, Drivers Overview

The CY2308SC-1T is a 3.3V zero delay buffer manufactured by Cypress Semiconductor Corp, housed in a 16-pin SOIC package with tape and reel packaging. It operates within a frequency range of 10 MHz to 133 MHz and features an on-chip PLL that locks to an input clock presented on the REF pin. The device provides eight outputs divided into two banks of four, which can be three-stated via select inputs. It achieves zero input-output propagation delay through capacitive load adjustment on the FBK input, ensuring low skew distribution for high-speed clock applications.

Clock Buffers, Drivers Feature Summary

• Zero input-output propagation delay adjustable by capacitive load on the FBK input
• Two banks of four outputs, three-stateable by two select inputs (S1, S2)
• 10 MHz to 133 MHz operating frequency range
• 75 ps typical cycle-to-cycle jitter at 66 MHz with 15 pF load

Clock Buffers, Drivers Applications

• PC clock distribution
• Workstation clock distribution
• Datacom clock distribution
• Telecom clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'T' confirms tape and reel packaging for the CY2308SC-1 variant. Confirm the 'C' suffix indicates commercial temperature range (0°C to 70°C). Ensure the specific configuration matches the required output frequencies, as this part corresponds to the base -1 configuration where output frequencies equal the reference.

Clock Buffers, Drivers Selection Notes

Select the CY2308SC-1T when a 1x frequency multiplication (reference to reference) is required. Use this part if surface-mount 16-pin SOIC packaging is preferred over TSSOP. Verify that the system load capacitance requirements align with the 15 pF or 30 pF limits specified for the target operating frequency to maintain jitter specifications.

Clock Buffers, Drivers Part Context

The CY2308 series includes variants such as -1H (high drive), -2, -3, -4, and -5H, offering different frequency multiplication options like 2x or 4x. The SC-1T specifically denotes the commercial grade, standard drive version in a tape and reel SOIC package. Other suffixes like SI denote industrial temperature ranges, while Z denotes TSSOP packages.
