ICS97ULP877BKLFT

Overview

The ICS97ULP877BKLFT is a low-power DDR2 memory clock driver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.7V to 1.9V and supports a maximum frequency of 410MHz. The device features a single circuit with a 1:10 input-to-output ratio, utilizing differential HCSL input and SSTL-18 output signaling. Packaged in a 40-VFQFPN (6x6) exposed pad format, it is designed for surface mount installation and functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports DDR2 memory applications with 1:10 fan-out capability
• Operates at frequencies up to 410MHz with 1.7V to 1.9V supply
• Features differential input/output signaling for noise immunity
• Integrated PLL for precise clock generation

Applications

• DDR2 memory subsystems
• High-speed data acquisition systems
• Telecommunications equipment requiring low-jitter clocks

Procurement Notes

Verify the package designation matches the 40-VFQFPN (6x6) specification. Confirm the supply voltage requirements align with the 1.7V to 1.9V range. Ensure thermal management strategies accommodate the exposed pad design for adequate heat dissipation during operation.

Selection Notes

Select this component when designing DDR2 interfaces requiring a 1:10 clock distribution. Compare against other Renesas ULP series devices if different fan-out ratios or voltage levels are needed. Verify that the SSTL-18 output compatibility matches the target memory controller specifications.

Part Context

This part belongs to the Renesas Ultra Low Power (ULP) family of clock drivers. It is specifically optimized for memory applications, offering low power consumption compared to standard voltage drivers while maintaining signal integrity for high-speed digital interfaces.

Replacement Considerations

Check for direct pin-compatible replacements within the same Renesas ULP series. Verify electrical parameters such as supply voltage and output drive strength before substituting with similar components from other manufacturers.
