85304AG-01LFT - Renesas Electronics

Description: The 85304-01 is a low skew, high performance 1-to-5 Differential-to-3.3V LVPECL fanout buffer and a member of the family of High Performance Clock Solutions from IDT. The 85304-01 has two selectable clock inputs. The CLKx, nCLKx pairs can accept most standard differential input levels. The clock enable is internally synchronized to eliminate runt clock pulses on the outputs during asynchronous assertion/ deassertion of the clock enable pin. Guaranteed output and part-to-part skew characteristics make the 85

85304AG-01LFT Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3804EU0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
  • Renesas recommends following their thermal design guidelines, using a heat sink if necessary, and ensuring proper airflow around the device. Additionally, the device's thermal protection feature can be enabled to prevent overheating.
  • Renesas recommends using a low-ESR ceramic capacitor (e.g., X5R or X7R) for CIN, with a value between 4.7uF to 10uF. For COUT, a low-ESR ceramic or electrolytic capacitor with a value between 10uF to 22uF is recommended.
  • Renesas recommends using a higher value for the input capacitor (CIN) and ensuring that the input voltage is within the specified range. Additionally, the device's UVLO (Under-Voltage Lockout) feature can be adjusted to optimize performance at low input voltages.
  • Renesas recommends using 1% or 0.1% tolerance resistors for RFB and RSENSE, with values between 1kΩ to 10kΩ for RFB and 10Ω to 100Ω for RSENSE, depending on the specific application requirements.
