ICS9248BF-81LFT

Overview

The ICS9248BF-81LFT is a frequency generator and buffer integrated circuit manufactured by Renesas Electronics Corporation. Designed for application-specific clock and timing requirements, this device features a single circuit with a 1:28 input-to-output ratio. It accepts crystal inputs and generates clock outputs with a maximum frequency of 133.3 MHz. The component operates within a supply voltage range of 3.135 V to 3.465 V and supports an operating temperature range of 0°C to 70°C. It is housed in a 48-BSSOP surface-mount package.

Feature Summary

• Integrated PLL frequency generation and buffering
• 1:28 input-to-output frequency ratio
• Crystal input interface
• Maximum output frequency of 133.3 MHz

Applications

• Application-specific clock distribution systems
• Timing circuits requiring precise frequency multiplication
• Digital logic synchronization interfaces

Procurement Notes

Verify the specific suffix 'BF-81LFT' against official Renesas documentation to confirm exact electrical tolerances and RoHS compliance status. Ensure the 48-SSOP package dimensions match the target PCB footprint. Confirm that the 0°C to 70°C commercial temperature range meets the operational environment requirements before procurement.

Selection Notes

Select this component when a fixed 1:28 frequency multiplication from a crystal source is required. The narrow 3.135 V to 3.465 V supply voltage range necessitates a stable power rail. Consider the 48-pin SSOP package size for board space constraints. Verify that the commercial temperature range is sufficient for the intended application environment.

Part Context

This part belongs to the Renesas application-specific clock and timing product line. It functions as a dedicated frequency generator and buffer, distinct from general-purpose oscillators or programmable clock generators. The device integrates phase-locked loop (PLL) technology to stabilize and multiply the input crystal frequency.
