Product details
Overview
AD8134ACPZ-REEL7 from Analog Devices is a triple high-speed differential driver IC designed for RGB video transmission over twisted-pair cable, featuring 225 MHz large-signal bandwidth, 1600 V/µs slew rate, fixed gain of 2, and integrated sync-on-common-mode circuitry for horizontal/vertical sync embedding. It drives 1.4 Vp-p video signals into doubly terminated 100 Ω UTP cable in KVM systems.
For engineers reviewing the AD8134ACPZ-REEL7 datasheet, AD8134ACPZ-REEL7 pinout, AD8134ACPZ-REEL7 application, or AD8134ACPZ-REEL7 equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated pin functions, confirmed alternatives, and supply support for industrial video infrastructure projects.
Technical Context
The AD8134ACPZ-REEL7 implements dual-loop feedback per channel: one loop controls differential output voltage (gain = 2), another independently regulates common-mode output voltage via internal sync circuitry. This architecture enables precise balance (−60 dB @ 50 MHz) without external tuning while supporting sync pulse injection onto RGB common-mode channels.
Each of its three amplifiers operates with differential input/output, supports single-ended-to-differential conversion, and maintains >80 dB inter-amplifier isolation at 10 MHz. The OPD pin provides fast (<100 ns) output pull-down to VS− + 0.82 V for differential multiplexing using external series diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Large-signal BW | 225 MHz (−3 dB, 2 Vp-p): supports full HD RGB video transmission over Cat-5 cable without attenuation-induced distortion. |
| Slew rate | 1600 V/µs: ensures minimal edge distortion on fast video transitions and sync pulses. |
| Output balance error | −60 dB @ 50 MHz: guarantees <0.1% amplitude/phase mismatch between ±OUT pairs, critical for EMI reduction in balanced lines. |
| Fixed gain | 2.0 V/V: compensates for 6 dB loss across doubly terminated 100 Ω UTP, eliminating need for external gain-setting resistors. |
| Quiescent current | 26.5 mA @ +5 V: enables low-power operation in multi-channel KVM transmitters without thermal derating. |
| Sync-on-CM capability | Integrated HSYNC/VSYNC processing with programmable level control: embeds timing signals into RGB common-mode channels without dedicated sync wires. |
| OPD response time | <100 ns assert/de-assert: allows rapid switching between active drivers on shared twisted-pair lines. |
Pinout & Package
The AD8134ACPZ-REEL7 is housed in a 24-lead 4 mm × 4 mm LFCSP package with exposed thermal pad (EPAD) requiring solder connection to PCB ground plane for thermal management and optimal electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OPD (Pin 1) | Output Pull-Down Control | Asserts low-voltage state on all outputs (VS− + 0.82 V) for differential multiplexing; threshold referenced to VS+. |
| VS− (Pins 2,5,14,21) | Negative Supply Rail | Common return for all three amplifiers and sync circuitry; must be decoupled with 0.1 µF capacitors. |
| +IN R/G/B (Pins 4,22,15) | Noninverting Inputs | Accept single-ended RGB inputs; input resistance = 1.13 kΩ (single-ended mode). |
| −IN R/G/B (Pins 3,23,16) | Inverting Inputs | Complete differential input pairs; differential input resistance = 1.5 kΩ. |
| +OUT R/G/B (Pins 7,9,12) | Positive Outputs | Drive one side of balanced RGB differential pair; swing = VS− + 1.25 V to VS+ − 1.15 V @ +5 V supply. |
| −OUT R/G/B (Pins 6,10,13) | Negative Outputs | Drive complementary side; matched to +OUT within −60 dB balance error up to 50 MHz. |
| HSYNC/VSYNC (Pins 19,20) | Sync Pulse Inputs | Accept TTL-compatible sync signals; enable common-mode sync embedding without external logic. |
| SYNC LEVEL (Pin 18) | Sync Amplitude Control | Sets amplitude of embedded sync pulses on RGB common-mode channels (gain ≈ 1.02 V/V to red/blue, 2.03 V/V to green). |
| VS+ (Pins 8,11,17,24) | Positive Supply Rail | Supports +5 V or ±5 V operation; PSRR = −54 dB ensures immunity to supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent drivers | Three fully isolated amplifiers (R/G/B) in single 4 mm × 4 mm LFCSP - reduces board area vs. discrete op-amp solutions by >60%. |
| Sync-on-common-mode | On-chip circuitry injects HSYNC/VSYNC into RGB common-mode channels - eliminates separate sync wiring and cuts EMI radiation by >20 dB. |
| Output pull-down (OPD) | Sub-100 ns activation pulls all outputs to VS− + 0.82 V - enables seamless differential multiplexing with external series diodes. |
| Internal common-mode feedback | Maintains −60 dB output balance error up to 50 MHz - ensures consistent differential signal integrity across temperature and supply variations. |
| Dual-supply flexibility | Operates from +5 V or ±5 V - simplifies integration into legacy analog video systems and modern single-rail designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple differential driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8130ARZ | Single-channel, lower bandwidth (350 MHz small-signal), no sync-on-CM, no OPD, SOIC-8 package | Requires three separate ICs for RGB; lacks integrated sync embedding and multiplexing control | Select when only one channel is needed or board space permits discrete implementation. |
| THS7374IPWPR | Triple 6 dB gain driver, 100 MHz bandwidth, no common-mode sync, no OPD, 24-pin TSSOP | Designed for SD/HD baseband video; insufficient bandwidth for full HD RGB; no sync-over-CM capability | Select for cost-sensitive SDTV applications where sync is carried separately and bandwidth ≤100 MHz suffices. |
Compared with AD8134ACPZ-REEL7, AD8130ARZ requires triple placement and external sync routing, while THS7374IPWPR lacks both sync-on-common-mode and output pull-down-making AD8134ACPZ-REEL7 uniquely suited for compact, EMI-conscious KVM and RGB-over-UTP systems demanding integrated timing and multiplexing.

FAQ
What is the operating temperature range for the AD8134ACPZ-REEL7?
The AD8134ACPZ-REEL7 is rated for operation from −40°C to +85°C, meeting extended industrial temperature requirements. Its thermal design-featuring an exposed paddle thermally connected to a PCB ground plane-ensures stable parametric performance across this full range, with quiescent current varying only ±10% and output balance error remaining within −60 dB up to 50 MHz.
Does the AD8134ACPZ-REEL7 support single-supply operation?
Yes, the AD8134ACPZ-REEL7 supports true single-supply operation at +5 V, with input common-mode voltage range of 0 V to 5 V and output swing from VS− + 1.25 V to VS+ − 1.15 V. It also operates from ±5 V supplies, offering design flexibility for legacy analog video systems and modern low-voltage architectures without performance compromise.
How does the sync-on-common-mode feature work in the AD8134ACPZ-REEL7?
The AD8134ACPZ-REEL7 integrates dedicated HSYNC and VSYNC inputs that modulate the common-mode voltage of each RGB differential pair. The SYNC LEVEL pin sets pulse amplitude (gain ≈ 1.02 V/V for red/blue, 2.03 V/V for green), allowing horizontal and vertical sync signals to be transmitted alongside video on the same twisted-pair conductors-eliminating separate sync wiring and reducing EMI.
What is the purpose of the OPD pin on the AD8134ACPZ-REEL7?
The OPD (Output Pull-Down) pin on the AD8134ACPZ-REEL7 enables fast (<100 ns) assertion of a low-impedance state on all six outputs, pulling them to VS− + 0.82 V. When used with external series diodes, this allows multiple AD8134ACPZ-REEL7 drivers to share a single twisted-pair cable without signal contention-ideal for KVM matrix switching and source multiplexing.
Can the AD8134ACPZ-REEL7 drive 100 Ω doubly terminated UTP cable directly?
Yes, the AD8134ACPZ-REEL7 is explicitly characterized to drive 100 Ω doubly terminated unshielded twisted-pair (UTP) cable with a 1.4 Vp-p video signal. Its fixed gain of 2 compensates for the 6 dB insertion loss inherent in double termination, and its 225 MHz large-signal bandwidth ensures minimal group delay and flat frequency response across the RGB video spectrum.
