Product details
Overview
The MAX9526ATJ+ from Maxim Integrated is a low-power, high-performance NTSC/PAL video decoder IC that converts composite video (NTSC M/J/4.43, PAL B/G/H/I/D/M/N/60) into 8-bit or 10-bit ITU-R BT.656 YCbCr component video. It features a 10-bit 54MHz ADC with 4× oversampling, internal line-locked PLL for LLC generation, and operates across the full automotive temperature range (–40°C to +125°C) in a 32-pin TQFN-EP package. Used in automotive entertainment and collision avoidance systems requiring robust analog front-end performance and minimal external components.
For engineers reviewing the MAX9526ATJ+ datasheet, MAX9526ATJ+ pinout, MAX9526ATJ+ application, or MAX9526ATJ+ equivalent, this page delivers verified technical context, confirmed pin functions, automotive-grade power and timing specifications, real-world application mappings, and two validated alternative decoders - all derived from Maxim's official documentation and electrical characteristics tables.
Technical Context
The MAX9526ATJ+ implements a fully integrated analog front-end with DC restoration DAC, analog AGC, and a 13MHz analog anti-aliasing filter - eliminating need for external filtering. Its 10-bit ADC samples at 54Msps with true 10-bit digital processing path and supports both line-locked (LLC mode) and asynchronous clocking modes via programmable PLL bandwidth (180Hz–2000Hz).
Digital decoding includes a 5-line adaptive comb filter for cross-chrominance/luminance artifact reduction, flexible output formatting (10-bit BT.656 with embedded TRS or 8-bit with separate HS/VS), and I²C-configurable registers (16 user-programmable) for brightness, contrast, saturation, and hue control - all operating from single 1.8V analog/digital supply and selectable 1.7V–3.45V I/O voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NTSC/PAL video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7180BCPZ | 10-bit ADC, 27MHz crystal, supports CVBS/S-video, no integrated analog LPF - requires external anti-aliasing filter | Broad industrial use; lacks automotive temp grade (–40°C to +85°C only) | Choose when external filtering is acceptable and extended temperature is not required |
| TVP5150AM1IPBS | 10-bit ADC, 27MHz clock, includes Y/C separation but no adaptive comb filter; higher typical power (350mW) | Legacy design reuse; supports S-video and Y/C inputs - broader analog input flexibility | Choose for multi-format analog input support where comb filtering is less critical |
Compared with ADV7180BCPZ and TVP5150AM1IPBS, the MAX9526ATJ+ uniquely integrates analog anti-aliasing filtering and delivers automotive-grade reliability with lower active power - making it optimal for space-constrained, thermally demanding ADAS modules where BOM reduction and temperature resilience are primary selection criteria.

FAQ
What video standards does the MAX9526ATJ+ support?
The MAX9526ATJ+ supports all major NTSC and PAL variants: NTSC M, NTSC J, NTSC 4.43, PAL B/G/H/I/D, PAL M, PAL N, and PAL 60. It automatically detects and configures for the incoming standard without host intervention. This behavior is confirmed in the General Description and Features sections of the MAX9526ATJ+ datasheet, and applies identically to the MAX9526ATJ+ variant in 32-pin TQFN-EP packaging.
Does the MAX9526ATJ+ require external anti-aliasing filtering?
No, the MAX9526ATJ+ includes an integrated analog anti-aliasing lowpass filter with 13MHz 3dB bandwidth and >36dB stopband attenuation at 53MHz. This eliminates the need for external RC or active filters on VIN1/VIN2, reducing BOM count and board area. The filter performance is specified in the Electrical Characteristics table and validated in Typical Operating Characteristics figure toc02.
What is the function of the NONSTD pin/status in the MAX9526ATJ+?
The NONSTD status (bit in Status register 0x00) indicates detection of nonstandard carrier frequencies - such as those from VCRs - and triggers automatic PLL reconfiguration into asynchronous sampling mode. This ensures robust decoding even with degraded or non-ITU-compliant inputs. The behavior is documented in the Detailed Description section and functional diagram of the MAX9526ATJ+ datasheet.
Can the MAX9526ATJ+ operate with a 54MHz external clock instead of a crystal?
Yes, the MAX9526ATJ+ accepts a 54MHz CMOS-level external clock applied to the XTAL/OSC pin when XTAL_DIS = 1 and SEL_54MHz = 1 (both set in register 0x0D). This bypasses the internal oscillator and allows precise clock sourcing - useful in systems where crystal layout is challenging or jitter-sensitive timing is required. Confirmed in the Crystal Oscillator/Clock Input subsection of the MAX9526ATJ+ datasheet.
What is the purpose of the EXPOSED PAD (EP) on the MAX9526ATJ+ TQFN package?
The exposed pad (EP) on the MAX9526ATJ+ is internally connected to DGND and must be soldered to a PCB thermal pad tied to digital ground. It provides critical thermal dissipation (enabling 1663mW max power on multilayer board) and improves EMI performance. The requirement is explicitly stated in the Pin Description table and Absolute Maximum Ratings section of the MAX9526ATJ+ datasheet.
