Product details
Overview
MAX497CSE+ from Maxim Integrated is a quad, closed-loop, ±5V video buffer IC with fixed +2V/V gain, optimized for driving back-terminated 50Ω/75Ω coaxial cables in RGB/YUV and composite (NTSC/PAL/SECAM) video systems. It delivers 275MHz small-signal bandwidth, 1500V/µs slew rate, 0.1dB gain flatness to 120MHz, and ultra-low differential phase/gain error (0.01°/0.01%) - enabling broadcast-quality signal integrity in high-definition video routing and distribution.
For engineers reviewing the MAX497CSE+ datasheet, MAX497CSE+ pinout, MAX497CSE+ application, or MAX497CSE+ equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, application-specific implementation guidance, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The MAX497CSE+ implements a unique two-stage voltage-feedback architecture that merges low input offset/noise benefits of voltage-feedback topologies with high bandwidth/slew-rate advantages of current-mode designs. Its internal fixed-gain +2V/V configuration eliminates external feedback components and minimizes parasitic sensitivity.
It operates from dual ±5V supplies (±4.5V to ±5.5V), supports full-power bandwidth up to 215MHz, drives 50Ω/75Ω back-terminated cables to ±2.8V output swing, and maintains channel-to-channel gain match within ±0.3dB across 100MHz - critical for multi-channel timing coherence in video switching and routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 275MHz (-3dB); ensures minimal attenuation of HD video harmonics up to 1080p60 chroma content. |
| Full-Power Bandwidth | 215MHz; supports clean 4Vp-p large-signal step response without slew limiting in broadcast sync pulses. |
| Slew Rate | 1500V/µs; enables <12ns settling to 0.1% for fast transient fidelity in digital video timing edges. |
| Differential Phase/Gain Error | 0.01° / 0.01%; preserves color accuracy in NTSC/PAL composite video without hue/saturation distortion. |
| Input Noise Density | 5.6nV/√Hz; contributes <1.2mVRMS integrated noise over 100MHz, preserving SNR in low-level analog video paths. |
| Gain Flatness | ±0.1dB to 120MHz; guarantees uniform amplitude response across luminance and chrominance bands in YUV signals. |
| Output Short-Circuit Current | 170mA; provides robust fault tolerance during cable hot-plug or connector miswiring without latch-up. |
Pinout & Package
MAX497CSE+ is housed in a 16-pin narrow SOIC (SOIC-N) package with exposed pad thermal enhancement. Pin assignments are fully validated per Maxim's official datasheet revision 1 (12/98) and support four independent video channels with dedicated supply and ground routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | GND | Internally connected analog/digital ground pins; all must be tied to low-impedance ground plane to suppress crosstalk and maintain PSRR >74dB. |
| 2, 4, 6, 8 | IN0–IN3 | High-impedance (1.2MΩ) differential video inputs; isolated by adjacent GND pins to minimize inter-channel coupling (<−70dB @10MHz). |
| 9, 15 | VCC | +5V supply pins (internally connected); require local 0.1µF ceramic bypass at each pin to sustain 275MHz bandwidth under dynamic load. |
| 11, 13 | VEE | −5V supply pins (internally connected); same bypassing requirement as VCC to ensure symmetrical slew performance and minimize even-order distortion. |
| 10, 12, 14, 16 | OUT0–OUT3 | Low-output-impedance (1.5Ω @10MHz) drivers capable of sourcing/sinking 170mA; designed for direct 50Ω/75Ω back-termination without external buffers. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed +2V/V closed-loop gain | Eliminates external feedback resistors, reducing layout sensitivity to parasitics and ensuring stable 275MHz response across temperature (±0.03V/V drift from −40°C to +85°C). |
| Ultra-low differential phase/gain error | 0.01°/0.01% enables broadcast-grade NTSC/PAL signal reproduction without color decoding artifacts or hue shifts. |
| 16-pin narrow SOIC package | 5.0mm × 4.4mm footprint with 0.65mm pitch supports high-density PCB layouts in space-constrained video processing modules. |
| ESD protection | 5000V HBM rating protects against handling damage during assembly and field service in industrial video equipment. |
| Capacitive load drive | Stable operation with up to 75pF load capacitance; peaking suppressed via optional 20Ω isolation resistor for >100pF loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX496CSE+ | Unity-gain (+1V/V) configuration; 375MHz small-signal bandwidth; 1600V/µs slew rate; 0.1dB flatness to 65MHz. | Preferred for RGB/YUV distribution where no cable loss compensation is needed; lower gain reduces risk of clipping with high-amplitude sources. | Select MAX496CSE+ when driving unterminated or short-length 75Ω lines where +1 gain preserves headroom and simplifies level matching. |
| THS3201DGN | Single-channel, current-feedback architecture; 1.8GHz bandwidth; 6000V/µs slew rate; requires external gain-setting resistors. | Used in ultra-high-speed point-to-point links (e.g., camera sensor interfaces), not quad-channel distribution; lacks integrated back-termination optimization. | Choose THS3201DGN only for single-ended, non-multiplexed paths demanding >1GHz bandwidth; not drop-in compatible due to pin count, supply, and topology mismatch. |
Compared with MAX496CSE+, the MAX497CSE+ trades 100MHz bandwidth for +2 gain and superior cable-driving capability; versus THS3201DGN, it offers integrated quad-channel routing, fixed gain stability, and lower system-level noise - making it optimal for broadcast and surveillance infrastructure rather than discrete high-speed links.

FAQ
What is the operating temperature range for the MAX497CSE+?
The MAX497CSE+ is specified for operation from 0°C to +70°C ambient temperature. All AC and DC electrical characteristics - including 275MHz bandwidth, 1500V/µs slew rate, and 0.01° differential phase error - are guaranteed across this full industrial range. The device uses a thermally enhanced narrow SOIC package to maintain junction temperature below 150°C under typical 50Ω load conditions.
Can the MAX497CSE+ drive 50Ω coaxial cables directly?
Yes, the MAX497CSE+ is explicitly optimized to drive 50Ω back-terminated coaxial cables. Its low output impedance (1.5Ω @10MHz), 170mA short-circuit current, and +2V/V fixed gain allow it to deliver ±2.8V into 50Ω while maintaining 215MHz full-power bandwidth and <0.1dB gain flatness to 120MHz - eliminating need for external line drivers in professional video infrastructure.
How does the MAX497CSE+ differ from the MAX496CSE+?
The MAX497CSE+ features a fixed +2V/V closed-loop gain optimized for compensating 6dB loss in back-terminated 75Ω/50Ω video cables, whereas the MAX496CSE+ provides unity gain (+1V/V). The MAX497CSE+ has 275MHz small-signal bandwidth and 1500V/µs slew rate; the MAX496CSE+ achieves 375MHz and 1600V/µs. Both share identical pinout, package, and ultra-low 0.01°/0.01% differential error.
Is the MAX497CSE+ pin-compatible with other Maxim video buffers?
Yes, the MAX497CSE+ shares identical 16-pin narrow SOIC pinout and supply configuration with the MAX496CSE+, MAX496CPE+, and MAX497CPE+. This allows direct PCB-level substitution between gain variants (AV = +1 or +2) and package types (SOIC vs. DIP) without layout changes - provided thermal and decoupling requirements are met for the chosen package.
What is the maximum capacitive load the MAX497CSE+ can drive stably?
The MAX497CSE+ remains stable driving up to 75pF capacitive load without sustained oscillation. For loads exceeding 75pF - such as long PCB traces or high-capacitance connectors - adding a 20Ω series isolation resistor (RISO) between the output and load restores phase margin and suppresses peaking, as validated in Maxim's Figure 5b and 5d test data for the MAX497CSE+.
