Product details
Overview
ADV7174WBCPZ from Analog Devices is a single-chip PAL/NTSC video encoder IC that converts 8-bit CCIR-656 YCrCb digital video into analog composite (CVBS), S-video (Y/C), or RGB/YPbPr outputs. It integrates three 10-bit DACs, a 32-bit DDS for subcarrier generation, SSAF™ filtering, CGMS-A, WSS, and Macrovision 7.1 (ADV7174 only), operating from a single 27 MHz clock and supporting −40°C to +85°C at 3.3 V. It targets portable video systems requiring multistandard analog output with advanced copy protection.
For engineers reviewing the ADV7174WBCPZ datasheet, ADV7174WBCPZ pinout, ADV7174WBCPZ application, or ADV7174WBCPZ equivalent, key selection considerations include its AEC-Q100 qualification, programmable luma/chroma filters (e.g., PAL/NTSC notch, extended SSAF), dual-mode timing (main/subordinate), real-time subcarrier locking, and 80 dB SNR performance in a compact 40-lead LFCSP package.
Technical Context
The ADV7174WBCPZ implements a fully integrated digital video encoding pipeline: CCIR-656 4:2:2 pixel data enters via an 8-bit multiplexed port synchronized to a 27 MHz clock (or 24.5454 MHz/29.5 MHz for square-pixel modes), undergoes programmable FIR filtering (luma up to 8.0 MHz stop-band, chroma up to 2.0 MHz low-pass), subcarrier modulation via 32-bit DDS, and luma delay alignment before DAC conversion. Its on-chip timing generator supports both main (output sync) and subordinate (accept sync) operation with HSYNC/FIELD/VSYNC bidirectional pins.
Power management includes three operational states-normal (120 mA IDAC max), low-power (62 mA IDAC), and sleep mode (0.1 µA IDAC)-with individual DAC enable/disable control. Macrovision 7.1 is exclusive to the ADV7174 variant and requires licensing for noncommercial home use; CGMS-A and WSS are implemented via dedicated registers and Teletext insertion port (TTX/TTXREQ) for PAL-WST compliance.

Applications
| Portable Media Players | Automotive Rear-Seat Entertainment |
|---|---|
|
Use Scenario: Compact handheld devices playing MPEG-2 video require analog output to legacy TVs or car monitors via composite or S-video. IC Role / Device Role / Timing Role: ADV7174WBCPZ acts as the final-stage video encoder, accepting CCIR-656 data from an SoC decoder and generating synchronized CVBS/Y/C with embedded WSS and CGMS-A. Use Value: Single-chip integration eliminates discrete DACs, filters, and timing logic; 80 dB SNR ensures clean playback on consumer displays. |
Use Scenario: In-vehicle infotainment systems deliver video to rear-seat screens using analog interfaces while meeting automotive reliability standards. IC Role / Device Role / Timing Role: ADV7174WBCPZ operates in main timing mode, generating precise PAL/NTSC sync signals and driving multiple analog outputs with AEC-Q100 assurance. Use Value: −40°C to +85°C operation, robust ESD protection, and integrated Macrovision support simplify compliance with automotive OEM requirements. |
| Digital Still Cameras | Set-Top Box Video Outputs |
|
Use Scenario: High-resolution cameras output recorded video to TVs via mini-USB or HDMI-to-analog adapters requiring legacy compatibility. IC Role / Device Role / Timing Role: ADV7174WBCPZ serves as a programmable video output bridge, converting YCrCb pixel data to NTSC/PAL with selectable pedestal and square-pixel timing. Use Value: Programmable luma/chroma filters (e.g., NTSC notch, PAL low-pass) optimize image quality for different display types without external components. |
Use Scenario: Broadcast STBs must support multistandard analog outputs (CVBS, S-video, RGB) alongside digital interfaces for global market deployment. IC Role / Device Role / Timing Role: ADV7174WBCPZ functions as a subordinate encoder, locked to incoming video timing while generating compliant analog waveforms with CGMS-A and teletext. Use Value: Simultaneous composite + S-video output capability reduces BOM count; I²C register access enables field-upgradable video formatting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar video encoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7179WBCPZ | Same pinout and core architecture but lacks Macrovision 7.1; supports identical PAL/NTSC standards, filters, and power modes | Targeted at non-copy-protected applications (e.g., industrial monitoring, medical imaging) where Macrovision licensing is unnecessary | Select ADV7179WBCPZ when Macrovision is not required-reduces licensing overhead and simplifies certification. |
| THS8200IPFP | TI 10-bit triple DAC encoder; supports NTSC/PAL but no built-in SSAF, CGMS, or WSS; requires external timing control and filtering | Suitable for cost-sensitive designs where system-level firmware handles copy protection and filter configuration | Choose THS8200IPFP only if external processing resources exist to replicate ADV7174WBCPZ's integrated features. |
Compared with ADV7174WBCPZ, ADV7179WBCPZ offers identical video quality and packaging without Macrovision licensing complexity, while THS8200IPFP demands additional design effort for timing, filtering, and copy protection-making ADV7174WBCPZ optimal for turnkey multistandard analog output with minimal external components.

FAQ
What video standards does the ADV7174WBCPZ support?
The ADV7174WBCPZ supports NTSC M/N (with and without pedestal) and PAL B/D/G/H/I/M/N standards. It also enables square-pixel operation using 24.5454 MHz (NTSC) or 29.5 MHz (PAL) input clocks. All modes are software-configurable via I²C registers, and waveform compliance is verified per ITU-R BT.601/BT.656 specifications in the datasheet.
Does the ADV7174WBCPZ include Macrovision support?
Yes, the ADV7174WBCPZ includes on-chip Macrovision 7.1 copy protection, which is exclusive to the ADV7174 variant (not present in ADV7179). This feature is licensed for noncommercial home use only, and implementation requires adherence to Macrovision's licensing terms-contact Analog Devices sales for version availability and compliance guidance.
How does the ADV7174WBCPZ handle power management?
The ADV7174WBCPZ provides three distinct power modes: normal (120 mA max IDAC), low-power (62 mA max IDAC), and sleep (0.1 µA IDAC). Individual DACs can be disabled to further reduce current, and the COMP pin allows dynamic capacitor tuning (0.1 µF down to 2.2 nF) for optimized low-power performance without sacrificing video fidelity.
Can the ADV7174WBCPZ generate both composite and S-video simultaneously?
Yes, the ADV7174WBCPZ supports programmable simultaneous outputs: composite (CVBS) + S-video (Y/C), composite + RGB (SCART), or YPbPr. This is configured via Mode Register settings and requires no external switching circuitry-DAC A, B, and C are independently assigned to output signals under firmware control.
What is the function of the SCRESET/RTC pin on the ADV7174WBCPZ?
The SCRESET/RTC pin on the ADV7174WBCPZ is multifunctional: configured via Mode Register 2 bits MR22/MR21, it serves either as a subcarrier reset input (low-to-high transition resets subcarrier to Field 0) or as a real-time control (RTC) input for dynamic subcarrier locking to external video sources like the ADV7183A decoder, enabling line-by-line frequency compensation.
