BU7325HFV-TR

Overview

The BU7325HFV-TR is a compact single-channel clock generator designed for digital still and video cameras. It generates high-frequency CCD, USB, and VIDEO clocks using a 27.0000 MHz reference input. The device operates on a single 2.85 V to 3.6 V supply with an operating temperature range of -30 °C to 85 °C. It provides two selectable output frequencies: 48.0000 MHz (SEL=L) and 78.0000 MHz (SEL=H). Typical operating currents are 11 mA and 12 mA respectively, with standby current below 1 µA when OE is low. Jitter performance is characterized by a 1σ period jitter of 50 psec.

Feature Summary

• Dual frequency selection via SEL pin: 48.0000 MHz or 78.0000 MHz from a 27.0000 MHz input
• Power-down function controlled by OE pin with typical standby current of 1 µA
• Compact HVSOF6 package suitable for space-constrained designs
• Low jitter performance with 50 psec typical 1σ period jitter

Applications

• Digital Still Cameras
• Digital Video Cameras
• CCD Clock Generation
• USB Clock Generation
• Video Signal Processing

Procurement Notes

Verify the specific suffix '-TR' against the manufacturer's official documentation to confirm reel packaging specifications. Confirm end-of-life status and availability through authorized distributors, as this component belongs to a series that may have discontinued variants. Ensure the ordering part number matches the exact electrical characteristics required for the target application.

Selection Notes

Select the BU7325HFV-TR when a 27 MHz reference crystal is available and either 48 MHz or 78 MHz outputs are required. Compare operating current requirements between the 48 MHz and 78 MHz modes if power consumption is critical. Verify that the HVSOF6 package dimensions fit the PCB layout constraints. Ensure the SEL pin logic levels align with the system control voltage.

Part Context

The BU7325HFV is part of ROHM's High-performance Clock Generator Series, which includes models like BU3071HFV, BU7322HFV, and others. These components share similar compact HVSOF6 packaging and power-down capabilities but differ in reference inputs and output frequencies. This series is specifically engineered to replace larger oscillators in portable imaging devices.

Replacement Considerations

BU7322HFV offers different output frequencies (49.5 MHz/36 MHz) with similar packaging. BU3076HFV uses a 27 MHz input but provides 54 MHz/67.5 MHz outputs. Check pin compatibility and electrical parameters before substitution.
