Product details
Overview
MAX7454UUP from Maxim Integrated is a triple-channel HD/SD switchable video reconstruction filter and buffer IC designed for component video output (Y/PB/PR or RGB) in consumer TV systems. It delivers +6dB gain, supports 1080i/720p/480p/480i scanning standards, features DC-coupled I/O, and drives 2VP-P into 150Ω loads - enabling compact, capacitor-free video signal conditioning in set-top boxes and HDTV displays.
For engineers reviewing the MAX7454UUP datasheet, MAX7454UUP pinout, MAX7454UUP application, or MAX7454UUP equivalent, key selection criteria include its 30MHz HD / 10MHz SD switchable lowpass response, ±0.25V total output DC variation, 0.1ns channel-to-channel group delay matching (HD mode), 70dB channel isolation, and compatibility with single +5V supply operation across 0°C to +85°C.
Technical Context
The MAX7454UUP integrates three identical elliptic-response lowpass filters with programmable HD/SD bandwidth selection via SD/HD and FSEL pins, enabling dynamic adaptation to 1080i (74MHz sampling), 720p (74MHz), 480p (27MHz), or 480i (27MHz) video standards. Each channel includes a DC-coupled output buffer optimized for 150Ω video loads without AC-coupling capacitors.
Filter response is digitally controlled: SD/HD selects between HD (30MHz passband) and SD (10MHz passband) modes, while FSEL fine-tunes cutoff to prioritize either passband flatness (FSEL = VCC) or stopband attenuation (FSEL = GND). Group delay deviation is ≤4ns (HD, 100kHz–26MHz) and ≤12ns (SD, 100kHz–10MHz), ensuring minimal timing distortion across channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | +6dB - matches standard video DAC output levels to 2VP-P video load requirements without external amplification |
| HD Passband Response | -2.3dB at 30MHz - preserves luminance/chroma fidelity up to full 1080i/720p bandwidth |
| SD Passband Response | -0.40dB at 10MHz - maintains color accuracy and edge integrity for 480p/480i signals |
| HD Stopband Attenuation | -55dB at 74MHz - suppresses aliasing artifacts from HDTV sampling harmonics |
| Supply Voltage | +4.75V to +5.25V - operates reliably from standard 5V rail with ±5% tolerance |
| Supply Current | 240mA typical - enables thermal design with 30°C/W max net thermal resistance on 2-layer PCB |
| Operating Temperature | 0°C to +85°C - qualified for upper commercial temperature range in set-top and display applications |
Pinout & Package
MAX7454UUP is housed in a 20-pin TSSOP-EP package with exposed pad (internally connected to GND) for enhanced thermal dissipation. The package measures 6.5mm × 4.4mm × 1.1mm and requires ground-plane copper under the EP for thermal management per Maxim's layout guidelines.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 11, 12, 15, 18 | GND | Eight dedicated ground terminals - minimize ground bounce and ensure stable reference for all three channels |
| 2, 4, 6 | IN1 / IN2 / IN3 | DC-coupled analog video inputs - accept 0–1.2V input range directly from DACs or encoders, no AC coupling required |
| 8 | SD/HD | Mode select: GND = HD (30MHz), VCC = SD (10MHz) - configures filter bandwidth for target video standard |
| 9 | FSEL | Frequency optimization: VCC = max passband flatness, GND = max stopband attenuation - trade-off control per application need |
| 10, 13, 16, 19 | VCC | Four +5V supply pins - distributed power delivery reduces IR drop and improves PSRR across channels |
| 14, 17, 20 | OUT3 / OUT2 / OUT1 | DC-coupled video outputs - drive 2VP-P into 150Ω loads; blank level <1V meets digital TV DC specification |
| EP | Exposed Pad | Internally grounded thermal pad - must be soldered to PCB ground plane with ≥21 vias for 25°C/W thermal resistance |
Key Features
| Feature | Design Value |
|---|---|
| Triple-channel HD/SD switchable filtering | Single IC replaces three discrete filters + buffers - reduces BOM count and board area in Y/PB/PR signal chains |
| DC-coupled input and output | Eliminates 10–100µF AC-coupling capacitors - avoids size, cost, and low-frequency droop issues in space-constrained designs |
| 0.1ns channel-to-channel group delay matching (HD) | Preserves inter-channel timing alignment critical for RGB/YUV color fidelity and chroma/luma synchronization |
| 70dB channel-to-channel isolation (DC–1MHz) | Prevents crosstalk-induced color bleeding or ghosting between video components in multi-channel routing |
| ±0.25V total output DC variation | Ensures consistent blanking level across temperature and supply - simplifies compliance with digital TV DC voltage limits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video reconstruction filter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX7455UUP | +12dB gain vs. MAX7454UUP's +6dB; otherwise identical pinout, specs, and functionality | Required when driving longer cables or higher-capacitance loads where 2VP-P output needs additional headroom | Select MAX7455UUP only if system-level signal chain analysis confirms need for +12dB gain - avoid overdriving downstream ADCs or receivers. |
| AD8129ARZ | Single-channel, fixed-gain (10V/V) video driver; no HD/SD switching, no integrated reconstruction filtering, higher supply current (30mA/channel) | Suitable for point-to-point video distribution but lacks triple-channel integration and programmable bandwidth | Use AD8129ARZ only for non-standard or custom video paths requiring ultra-low noise (<2nV/√Hz) - not a functional replacement for MAX7454UUP's integrated filter+buffer architecture. |
Compared with MAX7454UUP, MAX7455UUP offers higher gain for extended cable runs but identical timing and filtering behavior, while AD8129ARZ provides superior noise performance in single-channel applications but requires external filters and separate gain stages to match MAX7454UUP's integrated functionality.

FAQ
What video standards does the MAX7454UUP support?
The MAX7454UUP supports 1080i, 720p, 480p, and 480i scanning standards through its HD/SD switchable filter architecture. In HD mode (SD/HD = GND), it delivers a 30MHz passband suitable for 74MHz-sampled HDTV signals; in SD mode (SD/HD = VCC), it provides a 10MHz passband optimized for 27MHz-sampled SDTV. Both modes are fully specified over 0°C to +85°C.
How does the MAX7454UUP eliminate the need for AC-coupling capacitors?
The MAX7454UUP uses fully DC-coupled input and output stages, allowing direct connection to DACs and 150Ω video loads without large AC-coupling capacitors. Its output blank level is controlled to remain below 1V, meeting digital TV DC specifications. This eliminates capacitor-induced low-frequency droop, size penalties, and reliability concerns associated with 10–100µF electrolytic or tantalum capacitors.
What is the purpose of the FSEL pin on the MAX7454UUP?
The FSEL pin on the MAX7454UUP adjusts the filter's cutoff frequency to optimize either passband flatness or stopband attenuation. When FSEL = VCC, passband response is maximized (e.g., -2.3dB at 30MHz in HD mode); when FSEL = GND, stopband rejection is maximized (e.g., -55dB at 74MHz). This allows system designers to tailor MAX7454UUP performance to specific noise or fidelity requirements.
Can the MAX7454UUP be used in anti-aliasing applications?
Yes, the MAX7454UUP can serve as an anti-aliasing filter in analog-to-digital video sampling systems. Its steep elliptic response provides >62dB attenuation at 27MHz (SD) and >55dB at 74MHz (HD), effectively suppressing out-of-band noise before ADC conversion. The output may be DC- or AC-coupled depending on the ADC's input voltage range and blanking level requirements.
What thermal design considerations apply to the MAX7454UUP?
The MAX7454UUP's 20-pin TSSOP-EP package requires proper thermal management: the exposed pad must be soldered to a PCB ground plane using ≥21 vias, with copper area matching the package outline. On a 4-layer FR-4 board, this achieves ~25°C/W thermal resistance. For reliable operation at +85°C ambient, net thermal resistance must not exceed 30°C/W to keep junction temperature ≤150°C.
