CDCS503TPWRQ1

Overview

The CDCS503TPWRQ1 is an automotive-grade clock buffer and multiplier integrated circuit manufactured by Texas Instruments. It features a single LVCMOS input-to-LVCMOS output configuration with a 1:1 ratio, operating at a maximum frequency of 108 MHz. The device functions within a supply voltage range of 3 V to 3.6 V and supports surface mount installation in an 8-TSSOP package (4.40 mm width). Certified under AEC-Q100 standards, it ensures reliability for automotive applications across an extended temperature range from -40°C to +105°C.

Feature Summary

• AEC-Q100 qualified for automotive grade reliability
• Single-channel LVCMOS buffer/multiplier with 1:1 ratio
• Maximum operating frequency of 108 MHz
• Extended industrial temperature range (-40°C to +105°C)

Applications

• Automotive infotainment system clock distribution
• In-vehicle networking signal buffering
• ADAS sensor interface timing

Procurement Notes

Verify the specific ordering suffix 'TPWRQ1' against official Texas Instruments documentation to confirm the exact reel quantity and tape specifications. Ensure that the AEC-Q100 qualification status aligns with the target automotive application requirements before finalizing procurement decisions.

Selection Notes

Select this component when a robust, automotive-certified clock buffer is required for LVCMOS signals up to 108 MHz. The 8-TSSOP package suits space-constrained PCB layouts, while the wide operating temperature range accommodates harsh automotive environments without additional thermal management.

Part Context

This part belongs to the CDCS503 family of clock multipliers and buffers. The 'Q1' suffix indicates automotive qualification, while 'PWR' denotes the TSSOP package type. It serves as a specialized variant designed specifically for high-reliability automotive electronics compared to standard commercial counterparts.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the CDCS50x series or other AEC-Q100 qualified clock buffers from Texas Instruments to ensure functional equivalence.
