BU7322HFV-TR

Overview

The BU7322HFV-TR is a compact single-channel clock generator designed for digital still and video cameras. It generates high-frequency CCD, USB, and VIDEO clocks from a 27.0000 MHz reference input. The device operates on a single 3.3 V supply (range 2.85 V to 3.6 V) and features selectable output frequencies of 49.5000 MHz or 36.0000 MHz via the SEL pin. It includes a power-down function controlled by the OE pin, low jitter characteristics (50 psec typical), and is housed in an HVSOF6 package.

Feature Summary

• Single-channel clock generation with selectable outputs: 49.5000 MHz (SEL=L) or 36.0000 MHz (SEL=H).
• Low period-jitter performance with a typical standard deviation of 50 psec.
• Integrated power-down mode reducing standby current to 1 µA maximum when OE is Low.
• Compact HVSOF6 package suitable for space-constrained portable electronic devices.

Applications

• Digital Still Cameras
• Digital Video Cameras

Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to discontinuation. Confirm that the specific ordering suffix matches the required reel packaging specifications. Ensure compatibility with the 27.0000 MHz crystal input requirement before procurement.

Selection Notes

Select the BU7322HFV-TR when a 27.0000 MHz input clock is available and either 49.5000 MHz or 36.0000 MHz output is required. Compare against BU7325HFV if 48.0000 MHz or 78.0000 MHz outputs are needed instead. Ensure the application environment stays within the -5°C to 75°C operating temperature range specified for this variant.

Part Context

This component belongs to the High-performance Clock Generator Series by ROHM Semiconductor. It is grouped with similar models such as BU3071HFV, BU3072HFV, BU3073HFV, BU3076HFV, and BU7325HFV, which share the same HVSOF6 package form factor but differ in reference inputs and generated output frequencies.

Replacement Considerations

BU7325HFV offers alternative frequency outputs (48.0000 MHz / 78.0000 MHz) using the same 27.0000 MHz reference and HVSOF6 package. Pinout compatibility should be verified against other series members like BU3076HFV, though internal logic differs.
