Description:The 2309 is a low phase noise, high-speed PLL based, low-skew zero delay buffer. Based on ICS' proprietary low jitter Phase Locked Loop (PLL) techniques, the device provides nine low skew outputs at speeds up to 133 MHz at 3.3 V. The outputs can be generated from the PLL (for zero delay), or directly from the input (for testing), and can be set to tri-state mode or to stop at a low level. The PLL feedback is on-chip and is obtained from the CLKOUT pad. The 2309 is available in two different versions. The 23
Renesas provides a recommended PCB layout guide in their application note (R01AN4331EJ0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
Renesas recommends using an external overcurrent protection circuit, such as a current sense resistor and a comparator, to detect overcurrent conditions. The 2309-1HPGG also has a built-in overcurrent detection feature, but it's not enabled by default and requires external resistors to set the detection threshold.
While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends derating the device's performance at high temperatures (above 85°C) to ensure reliable operation and prevent thermal shutdown.
Yes, the 2309-1HPGG is designed to withstand vibrations up to 10G (10 Hz to 2 kHz) according to Renesas' vibration test standards. However, it's essential to follow proper PCB design and assembly guidelines to ensure the device's reliability in high-vibration environments.
Renesas provides a troubleshooting guide in their application note (R01AN4331EJ0100) which covers common issues with the voltage regulator, such as output voltage deviations, oscillations, and shutdown. The guide also provides guidance on debugging techniques and fault detection.
