Description:The 87002-02 is a highly versatile 1:2 Differential-to- LVCMOS/LVTTL Clock Generator. The 87002-02 has a differential clock input. The CLK, nCLK pair can accept most standard differential input levels. Internal bias on the nCLK input allows the CLK input to accept LVCMOS/LVTTL. The 87002-02 has a fully integrated PLL and can be configured as zero delay buffer, multiplier or divider and has an input and output frequency range of 15.625MHz to 250MHz. The reference divider, feedback divider and output divider
Renesas provides a recommended PCB layout guide in their application note (APL-AN-114) for the 87002AG-02LF. It suggests using a 4-layer PCB with a solid ground plane, placing the device near the center of the board, and using thermal vias to dissipate heat.
To ensure reliable operation in high-temperature environments, it's essential to follow Renesas' recommended operating conditions, including derating the output current and voltage according to the temperature. Additionally, consider using a heat sink or thermal interface material to reduce the junction temperature.
The 87002AG-02LF has built-in ESD protection diodes on all pins, which can withstand up to ±2 kV human body model (HBM) and ±200 V machine model (MM) ESD events. To prevent latch-up, Renesas recommends following proper PCB design and layout guidelines, such as minimizing signal trace lengths and using guard rings around sensitive nodes.
Yes, the 87002AG-02LF is AEC-Q100 qualified, making it suitable for automotive applications. However, it's essential to follow Renesas' guidelines for automotive applications, including ensuring the device operates within the recommended temperature range and using proper PCB design and layout techniques to minimize electromagnetic interference (EMI).
Renesas recommends storing the 87002AG-02LF in a dry, cool place, away from direct sunlight and moisture. When handling the device, use anti-static wrist straps, mats, or bags to prevent ESD damage. Avoid bending or flexing the leads, and use a vacuum pick-up tool or tweezers to handle the device.
