9FGV1005A003LTGI8

Overview

The Renesas 9FGV1005A003LTGI8 is a clock generator and jitter attenuator designed for high-performance digital systems. It features an integrated voltage-controlled crystal oscillator (VCXO) and supports multiple output frequencies derived from a single reference input. The device operates with low power consumption and offers programmable frequency multiplication and division ratios via I2C interface. Key electrical characteristics include a supply voltage range of 1.8V to 3.3V, output slew rate control, and differential LVPECL/LVDS outputs. It is engineered to reduce jitter in data transmission paths, ensuring signal integrity for high-speed interfaces.

Procurement Notes

Verify the specific suffix LTGI8 against the manufacturer's current datasheet to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing PCB footprint and thermal requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when jitter attenuation and frequency synthesis are required from a single reference source. Confirm that the required output frequencies fall within the device's operational range. Verify that the system power budget aligns with the device's low-power specifications. Check interface compatibility for I2C configuration.

Part Context

This model belongs to Renesas' 9FGV series of clock generators, which are widely used in telecommunications and computing infrastructure. The series is known for integrating VCXO functionality to simplify design by reducing external component count.
