Key Differentiators
- Automotive AEC-Q100 qualification (vs CDCE6214TWRGER)
- Ultra-low power consumption (vs LMK5C33216RGCR)
- Small footprint (vs CDCM6208VFRGZR)
Design Notes
Decouple the VDD pins with 0.1uF and 1uF capacitors placed as close as possible to the pins. Use a low-ESR ceramic capacitor for high-frequency noise. The device operates from a 3.3V supply; ensure the supply is clean and stable to minimize jitter.
Route differential output pairs with controlled impedance (e.g., 100Ξ© differential) and keep trace lengths matched. Avoid vias on high-speed clock traces if possible. Place the device close to the load to minimize skew and signal degradation.
Ensure the EEPROM select pin (SEL) is properly configured to select the desired page. Do not leave unused inputs floating; tie them to GND or VDD as appropriate. Verify the output driver mode matches the load requirements to avoid signal integrity issues.
Compliance Information
AEC-Q100 qualified per TI product page. RoHS compliant. REACH compliance assumed based on TI's global compliance.
