BU2365FV-E2

Overview

The BU2365FV-E2 is a clock generator IC designed for A/V equipment, featuring a built-in VCXO and PLL technology. It generates multiple high C/N clocks from a single crystal input. Key outputs include 33.8688 MHz or 36.864 MHz (selectable via FSEL), 18.432 MHz, 24.576 MHz, 54 MHz, and two buffered 27 MHz signals. The device operates on a single 3.0 V to 3.6 V supply with typical consumption of 55 mA. It utilizes an SSOP-B24 package and supports power-down mode with 0 µA standby current.

Feature Summary

• Built-in high-precision VCXO for synchronization with DVD Video clocks
• Generates multiple clocks including 33.8688/36.864 MHz, 18.432 MHz, 24.576 MHz, 54 MHz, and dual 27 MHz buffers
• Half-pulse clock protection function prevents asynchronous droop during frequency switching
• Power-down function reduces current consumption to 0 µA (typical)

Applications

• DVD recorders

Procurement Notes

Verify the EOL status and last-time buy availability through authorized distributors. Confirm RoHS compliance details as specified in the product documentation. Ensure the SSOP-B24 package dimensions match the target PCB footprint before procurement.

Selection Notes

Select this component for systems requiring precise video clock synchronization via VCXO. Ensure the external crystal oscillator meets the recommended specifications (e.g., Rd=30Ω, CL=10pF). Verify that the load capacitance requirements for each output pin are met by the circuit design to maintain jitter performance.
