Product details
Overview
ZXFV203EV from Diodes Incorporated is a triple-channel high-speed video amplifier IC designed for RGB component video buffer/driver applications. It delivers 210MHz gain-bandwidth, 380V/µs slew rate, and 0.04% differential gain with ±5V supply operation, enabling precise analog video signal conditioning in broadcast and professional AV equipment.
For engineers reviewing the ZXFV203EV datasheet, ZXFV203EV pinout, ZXFV203EV application, or ZXFV203EV equivalent, key selection criteria include differential gain/phase performance, 300pF load drive capability, 40mA output current per channel, and SO-14 package compatibility with legacy video routing designs.
Technical Context
The ZXFV203EV integrates three identical high-speed op-amp channels in a single SO-14 package, each configured as a unity-gain stable voltage feedback amplifier optimized for composite and component video signals. Its architecture supports DC-coupled and AC-coupled configurations with internal compensation for 210MHz bandwidth at G=1–3dB.
Each channel operates independently with rail-to-rail output swing under ±5V supplies, maintains 0.1dB flatness to 25MHz, and sustains specified performance driving up to 300pF capacitive loads-critical for long cable runs and multi-point video distribution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (G=1) | 210MHz - enables full HD (1080p) baseband video signal amplification without high-frequency roll-off |
| Slew Rate | 380V/µs - supports fast transient response for sharp video edge reproduction |
| Differential Gain | 0.04% - ensures minimal color saturation error in RGB/YUV analog video paths |
| Differential Phase | 0.04° - preserves hue fidelity across wide frequency range in broadcast-grade systems |
| Output Current | 40mA @ 3V - drives standard 75Ω video lines and multiple downstream inputs simultaneously |
| Supply Voltage | ±5V - compatible with legacy analog video signal chain power rails |
| Load Drive | Up to 300pF - accommodates PCB trace capacitance and connector parasitics in compact AV modules |
Pinout & Package
Package: SO-14 (Small Outline, 14-pin, 150mil width), JEDEC MS-012AC compliant, surface-mount with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 6, 10 | Non-inverting Input (+) | DC-bias reference or signal injection point per channel |
| 3, 7, 11 | Output | Capable of sourcing/sinking 40mA into 75Ω or 300pF loads |
| 4 | V− Supply | Common negative rail connection for all three amplifiers |
| 12 | V+ Supply | Common positive rail connection for all three amplifiers |
| 8, 13, 14 | NC | No-connect pins; electrically isolated and must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Triple-channel integration | Replaces three discrete SO-8 op-amps with one SO-14 device, reducing board area by ~40% in RGB video routing |
| 0.1dB bandwidth | 25MHz - meets SMPTE 259M and ITU-R BT.601 analog video flatness requirements |
| Low distortion profile | 0.04% DG / 0.04° DP - eliminates visible color shift in calibrated studio monitors |
| Capacitive load stability | Characterized to 300pF - eliminates need for external isolation resistors in typical video PCB layouts |
| Supply current | 7.5mA per channel - enables low-power active video distribution in fan-out architectures |
Applications
| RGB Component Video Distribution | Professional Broadcast Monitor Input Buffer |
|---|---|
Use Scenario: Routing RGBS signals from graphics card or scaler to multiple display inputs in control room wall displays. IC Role / Device Role / Timing Role: Triple-channel unity-gain buffer isolating source impedance and driving three parallel 75Ω coaxial lines. Use Value: Maintains 0.04% differential gain across all channels, preventing inter-channel color skew during simultaneous output. | Use Scenario: Conditioning analog RGBHV signals before ADC sampling in 4K-capable broadcast monitor front-end. IC Role / Device Role / Timing Role: High-fidelity post-equalization buffer stage ensuring flat 25MHz response prior to digitization. Use Value: 210MHz bandwidth prevents aliasing artifacts; 380V/µs slew rate preserves sub-nanosecond pixel timing integrity. |
| Legacy CCTV Matrix Switch Output Stage | Medical Imaging Display Interface |
Use Scenario: Driving long coaxial runs (up to 100m) from analog matrix switcher outputs to remote security monitors. IC Role / Device Role / Timing Role: Compensated video driver delivering 40mA into 75Ω + 300pF total load per channel. Use Value: Eliminates need for external series termination; 300pF drive rating matches typical BNC connector + cable parasitic capacitance. | Use Scenario: Signal conditioning between diagnostic ultrasound processor and analog RGB display panel in portable imaging units. IC Role / Device Role / Timing Role: Low-noise, DC-coupled buffer preserving grayscale linearity and contrast fidelity. Use Value: ±5V operation matches medical-grade analog subsystem rails; 0.04° differential phase prevents false-color artifacts in grayscale Doppler overlays. |
Availability

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design centers across Asia and manufacturing in China, Taiwan, and the U.S.
The ZXFV video amplifier product line targets high-fidelity analog video signal conditioning for broadcast, professional AV, and industrial imaging applications where differential gain/phase accuracy and wide bandwidth are non-negotiable.
FAQ
Is ZXFV203EV still in production?
No. Diodes Incorporated officially discontinued ZXFV203EV as of August 2020, marking it "OBSOLETE – PART DISCONTINUED" in DS43004 Rev. 6-4. Aetrix Electronics provides remaining inventory with full traceability and supports last-time-buy programs for legacy system maintenance.
What is the recommended replacement for ZXFV203EV?
Diodes Incorporated does not list an official drop-in replacement. Engineers commonly migrate to the AP3413TR-G1 (triple video amp, 200MHz, 0.05% DG) or THS3203DR (Texas Instruments, 375MHz, ±5V, 0.02% DG), though both require layout and biasing adjustments due to differing pinouts and quiescent current profiles.
Can ZXFV203EV operate on single-supply rails?
No. The device is specified only for dual ±5V operation per the Absolute Maximum Ratings and Electrical Characteristics tables. Attempting single-supply use (e.g., 0V/10V) violates its internal bias architecture and results in undefined output behavior and potential damage.
Does ZXFV203EV support DC-coupled video signals?
Yes. The amplifier's input common-mode range includes ground, and its output swings rail-to-rail under ±5V, enabling true DC-coupled operation required for sync-on-green, RGBHV, and other baseband video formats where DC level carries timing or blanking information.
