CY29948AXC

Clock Buffers, Drivers Overview

The CY29948AXC is a low-voltage clock buffer and driver manufactured by Cypress Semiconductor Corp. It features a 1:12 fanout distribution capability with two selectable LVCMOS, LVPECL, or LVTTL inputs. The device supports maximum frequencies of 200 MHz and operates on a supply voltage ranging from 2.375V to 3.63V. Outputs are compatible with LVCMOS and LVTTL standards. It is housed in a 32-TQFP package (7x7 mm) designed for surface mount applications.

Clock Buffers, Drivers Feature Summary

• Supports 200 MHz clock frequency with 2:12 input-to-output ratio
• Compatible with LVCMOS, LVPECL, and LVTTL input signals
• Operates within a 2.375V to 3.63V supply voltage range
• Housed in a 32-TQFP (7x7 mm) surface-mount package

Clock Buffers, Drivers Applications

• Clock distribution in nested synchronous systems
• Signal buffering for high-speed digital circuits
• System timing architecture requiring multiple clock outputs

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'XC' against official Cypress documentation to confirm temperature grade and RoHS compliance status. Confirm current availability as this component may be subject to discontinuation or lifecycle changes. Ensure the 32-TQFP package dimensions match the target PCB footprint requirements before ordering.

Clock Buffers, Drivers Selection Notes

Select the CY29948AXC when a single clock source needs to drive up to twelve downstream loads. Ensure the system voltage falls between 2.375V and 3.63V. Verify that the input signal type matches one of the supported LVCMOS, LVPECL, or LVTTL standards. Consider thermal performance if operating near the upper limit of the 0°C to 70°C range.

Clock Buffers, Drivers Part Context

This component belongs to the Cypress clock buffer and driver family. It serves as a multiplexer and fanout buffer for distributing clock signals in complex electronic designs. The device integrates input selection logic to manage primary and test clock sources efficiently.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible replacements within the same Cypress series. Verify that any substitute component maintains the 200 MHz frequency requirement and supports the necessary input/output voltage levels.
