Description:The 8V97051 is a high performance Wideband RF Synthesizer / PLL optimized for use as the local oscillator (LO) in Multi-Carrier, Multi-mode FDD & TDD Base Station radio card. It is offered in a compact 5x5, 32-VFQFN package. The 8V97051 Wideband RF Synthesizer / PLL offers a default Fractional Mode with the option to use it with an Integer mode. It requires an external loop filter. The 8V97051 with integrated Voltage Controlled Oscillator (VCO) supports output frequencies from 34.375MHz to 4400MHz and maint
Renesas provides a recommended PCB layout guide in their application notes (e.g., AN983) and design guides (e.g., DG9705). It's essential to follow these guidelines to ensure optimal performance, especially for high-frequency signals.
For optimal jitter performance, it's recommended to use a high-quality clock source with a low jitter specification. Additionally, ensure the clock input is properly terminated, and the clock signal is clean and free from noise. Renesas provides guidelines for clock input configuration in their application notes.
The 8V97051NLGI8 is rated for industrial temperature range operation, which is typically -40°C to 85°C. However, it's essential to check the specific temperature range for your application and ensure the device is operated within the recommended range to maintain reliability and performance.
Renesas recommends a specific power sequencing scheme to ensure proper device operation. This typically involves powering up the VDD and VDDA pins simultaneously, followed by the VDDO pin. The exact sequence may vary depending on the application, so it's essential to consult the datasheet and application notes for specific guidance.
Renesas recommends using high-quality, low-ESR decoupling capacitors with a value of 0.1 μF to 1 μF, depending on the application. It's essential to place these capacitors close to the device's power pins to ensure effective noise filtering and decoupling.
