2305B-1DCG8 - Renesas Electronics

Description: The 2305B is a high-speed phase-lock loop (PLL) clock buffer, designed to address high-speed clock distribution applications. The zero delay is achieved by aligning the phase between the incoming clock and the output clock, operable within the range of 10 to 133MHz. The 2305B is an 8-pin version of the 2309B. The 2305B accepts one reference input, and drives out five low skew clocks. The -1H version of this device operates, up to 133MHz frequency and has a higher drive than the -1 device.

2305B-1DCG8 Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3804EU0100) which includes thermal vias, copper pours, and component placement guidelines to ensure optimal thermal performance.
  • Renesas recommends using an external overcurrent protection circuit, such as a current sense resistor and a comparator, to detect overcurrent conditions. The 2305B-1DCG8 also has a built-in overcurrent detection feature, but it's not enabled by default and requires external resistors to set the detection threshold.
  • Although the datasheet doesn't specify a maximum voltage for the EN pin, Renesas recommends keeping it within the VCC voltage range (typically 3.3V or 5V) to ensure proper operation and prevent damage to the device.
  • The 2305B-1DCG8 is rated for operation up to 125°C, but Renesas recommends derating the output current and voltage to ensure reliable operation at high temperatures. Consult the datasheet and application notes for specific guidelines.
  • Renesas provides a troubleshooting guide in their application note (R01AN3804EU0100) which covers common issues, such as output voltage regulation, overcurrent protection, and thermal shutdown. Additionally, Renesas offers a dedicated support team and online resources for further assistance.
