AD8148ACPZ-R7

Overview

The AD8148ACPZ-R7 is a triple high-speed fully differential driver designed for wideband video applications. It features a fixed gain of 4 V/V, a 700 MHz large signal bandwidth, and a 3000 V/μs slew rate. The device operates on a supply voltage range of +4.5 V to ±5.5 V with a quiescent current of 62.5 mA. It includes an internal common-mode feedback network and sync-on-common-mode encoding capabilities.

Feature Summary

• Triple differential driver architecture with fixed gain of 4 V/V
• Internal common-mode feedback for balanced output amplitude and phase
• On-chip sync-on-common-mode encoding for vertical and horizontal sync signals
• Output pull-down feature enabling line isolation and differential multiplexing

Applications

• QXGA or 1080p video transmission
• Video over unshielded twisted pair (UTP)
• Differential signal multiplexing
• KVM networking

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the component matches the Analog Devices AD8148 series specifications. Ensure the LFCSP-24 package type aligns with board layout requirements. Check for RoHS compliance documentation as per manufacturer standards.

Selection Notes

Select this component for applications requiring high-speed differential signaling with a fixed gain of 4. It is suitable for driving UTP cables or PCB transmission lines. Consider the AD8146 or AD8147 if a different gain or common-mode control scheme is required instead of sync encoding.

Part Context

This part belongs to the AD8146/AD8147/AD8148 family of triple differential drivers manufactured by Analog Devices. These devices are built on the second-generation XFCB bipolar process to support high-resolution video signals up to 1080p.

Replacement Considerations

The AD8146ACPZ-R7 and AD8147ACPZ-R7 are functionally related parts within the same datasheet. Substitution requires verifying gain differences (2 V/V vs 4 V/V) and common-mode control features.
