Product Overview
The AD8147ACPZ-R7 is a triple differential high-speed video driver from Analog Devices (ADI), designed for long-distance YPbPr/RGBHV graphic signal transmission over Cat5/Cat6 UTP cables. It integrates 3 independent differential drivers with fixed gain of 2 (+6 dB) to offset line termination attenuation. Built-in sync-on-common-mode circuit embeds H/V sync into channel common-mode voltage, removing extra sync wiring. Featuring 780 MHz -3dB small-signal bandwidth and 3000 V/μs slew rate, it eliminates ghosting and color distortion for long cable runs. Housed in 24-LFCSP 4×4mm package, shipped on 7-inch tape & reel (1500pcs/reel), it serves as compact signal transmission core for AV matrix, digital signage and analog surveillance equipment.
Core Advantages
Integrated Sync-on-Common-Mode Matrix
Embeds H/V sync signals into channel common-mode voltage, cuts required cable pairs from 5 to 3 differential lines.
Ultra-Wide High-Speed Bandwidth Profile
780 MHz small-signal bandwidth with low distortion, supports UXGA/1080p HD video; 200 MHz 0.1dB flat bandwidth ensures stable color rendering.
Outstanding High Slew Rate Dynamics
3000 V/μs differential slew rate delivers fast signal edge response for long capacitive twisted pairs, with broadcast-grade low differential gain & phase error.
Simplified Layout and Stable Gain Factor
Factory-trimmed fixed gain of 2 (+6 dB) omits external gain resistors, simplifies PCB layout, reduces stray capacitance and guarantees consistent gain accuracy.

Frequently Asked Questions
Q1: Are AD8147ACPZ-R7 components genuine original?
A: All stock are brand-new original ADI factory parts. Every batch undergoes strict incoming QC with full lot traceability. Products are packed in original ESD tape & reel to prevent pad oxidation and moisture damage.
Q2: How does sync-on-common-mode work?
A: This tech embeds H/V sync signals into channel common-mode voltage without extra cable pairs. One Cat5/Cat6 cable with 3 twisted pairs transmits RGB video + sync together, cutting wiring costs and simplifying system design.
Q3: What do CP, Z and R7 mean in AD8147ACPZ-R7?
A: CP = LFCSP lead frame package; Z = RoHS lead-free matte tin finish; R7 = 7-inch tape & reel with 1500 pcs per reel, fully compatible with SMT automatic pick-and-place machines.
Q4: Why is the gain fixed at 2 (+6 dB) instead of adjustable?
A: It compensates standard 6dB attenuation from 50Ω source/receiver termination on 100Ω UTP cables. The built-in +6dB gain recovers signal loss and achieves flat 0dB unity gain at display terminals.
