ICS93716AF

Overview

The ICS93716AF is a DDR clock driver and buffer manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.3V to 2.7V and supports a maximum frequency of 233MHz. The device features a single circuit configuration with a 1:6 multiplication/division factor, converting one input clock into six output clocks. Designed for memory applications, it utilizes a 28-SSOP package with a width of 5.30mm. The component is rated for an operating temperature range of 0°C to +85°C and employs surface mount technology for PCB integration.

Feature Summary

• DDR Clock Driver with 1:6 output distribution ratio
• Maximum operating frequency of 233 MHz
• Low skew and low jitter PLL architecture
• I2C interface for functional and output control

Applications

• DDR memory subsystems
• System-on-Chip (SoC) clock distribution
• High-speed digital data transmission interfaces

Procurement Notes

Verify the specific suffix (e.g., A, FLF) against official datasheets to confirm package type and lead-free status. Confirm current availability as this series may be discontinued or subject to limited stock. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select based on the required output count and frequency stability. The 1:6 ratio suits designs needing multiple synchronized clock domains from a single source. Verify that the 2.3V–2.7V supply voltage aligns with the system power rails. Consider the SSOP package constraints for high-density layouts and ensure thermal management meets the 0°C to +85°C operational requirements.

Part Context

This component belongs to the Renesas/ICS 93716 family of clock drivers. These devices are engineered for low-power, high-performance memory systems. The family typically includes variants with different packages such as TSSOP and SSOP, offering flexibility in board design while maintaining consistent electrical performance characteristics for DDR applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas 93716 series, such as the 93716AGLF or 93716BGLF, which offer similar functionality in different package formats like TSSOP. Verify that any substitute maintains the 1:6 ratio and 233MHz frequency capability.
