Description:The MK2058-01 is a VCXO (Voltage Controlled Crystal Oscillator) based clock jitter attenuator designed for system clock distribution applications. This monolithic IC, combined with an external inexpensive quartz crystal, can be used to replace a more costly hybrid VCXO retiming module. The device accepts and outputs the same clock frequency in selectable ranges covering 4 kHz to 27 MHz. A dual input mux is also provided. By controlling the VCXO frequency within a phase-locked loop (PLL), the output clock is
Renesas provides a recommended PCB layout guide in their application note (APN) documents, which can be found on their website. The guide includes layout considerations for noise reduction, thermal management, and signal integrity.
Renesas recommends using a low-ESR capacitor (e.g., 0.1 μF) for power supply decoupling, and placing it as close as possible to the VCC pin. Additionally, a 10 μF capacitor is recommended for input voltage filtering. Refer to the datasheet for specific power supply requirements.
The MK2058-01SILFTR has an operating temperature range of -40°C to +125°C, but it's essential to note that the device's performance and reliability may degrade at extreme temperatures. Consult the datasheet for thermal management guidelines.
Renesas provides a troubleshooting guide in their application notes and technical support resources. Common issues can be related to incorrect pin configuration, power supply noise, or signal integrity problems. Consult the datasheet and application notes for guidance on troubleshooting and debugging.
Yes, Renesas recommends following proper EMI/EMC design practices, such as using shielding, grounding, and filtering to minimize electromagnetic interference. The datasheet provides guidelines for EMI/EMC considerations, and Renesas also offers application notes and technical support resources for EMI/EMC design.
