Product details

Overview

TDA9885HN/V5 from NXP Semiconductors is a multistandard PAL/NTSC vision and sound IF Phase-Locked Loop (PLL) demodulator IC for negative modulation only, operating at 5 V supply, supporting VIF frequencies up to 58.75 MHz, delivering 2.0 V (p-p) composite video output, and featuring I²C-bus control for full configuration in TV and STB signal processing chains.

For engineers reviewing the TDA9885HN/V5 datasheet, TDA9885HN/V5 pinout, TDA9885HN/V5 application, or TDA9885HN/V5 equivalent, this device serves as an alignment-free, digitally assisted IF-PLL demodulator with integrated sound carrier traps (4.5–6.5 MHz), precise AFC detection (±2.3 MHz acquisition window), and dual-mode SIF processing (QSS/intercarrier), critical for legacy analog broadcast receiver design and repair.

Technical Context

The TDA9885HN/V5 implements a dual-loop architecture: a vision IF PLL with fully integrated VCO (50–140 MHz range, divided-by-two for quadrature outputs) and a narrowband FM-PLL demodulator (4–7 MHz VCO) for sound. It uses AC-coupled differential VIF/SIF amplifiers with 66 dB gain control range and sync-level–based AGC for negative modulation.

Its digital acquisition help enables lock-in across six VIF frequencies (33.4–58.75 MHz) via I²C-programmable thresholds, while the 4-bit AFC DAC provides readable frequency error data and analog current output at pin AFC. The device supports single-reference Quasi Split Sound (QSS) mixing and intercarrier mode switching via I²C, with no external crystal required when using the 4 MHz REF input as oscillator.

Equivalent & Alternatives

The following parts are listed as comparable options for similar IF-PLL demodulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDA9886HN/V5	Supports PAL/SECAM/NTSC, positive/negative modulation, and AM sound demodulation - adds SECAM L/L' compatibility and gated phase detector.	Required for SECAM broadcast regions (France, Russia, Eastern Europe); not pin-compatible due to additional functionality on pins 32 and 16.	Select TDA9886HN/V5 only if SECAM support or positive-modulation capability is mandatory; otherwise TDA9885HN/V5 offers lower cost and identical footprint for PAL/NTSC-only designs.
LA76818N	Single-chip TV signal processor with integrated tuner interface, chroma decoder, and OSD - lacks dedicated VIF/SIF PLLs and uses different AGC architecture.	Targets full TV SoC replacement rather than discrete IF demodulation; requires redesign of signal chain and power delivery.	LA76818N is not a drop-in alternative; consider only for new designs where system integration outweighs legacy IF stage reuse.

Compared with TDA9886HN/V5, the TDA9885HN/V5 omits SECAM support and positive-modulation handling but retains identical HVQFN32 packaging, I²C register map (for shared functions), and VIF/SIF performance - making it the optimal choice for cost-sensitive PAL/NTSC-only applications requiring minimal BOM change.

FAQ

What modulation standards does the TDA9885HN/V5 support?

The TDA9885HN/V5 supports PAL and NTSC vision and sound IF signals with negative modulation only. It does not support SECAM, positive modulation, or AM sound demodulation - those capabilities are exclusive to the TDA9886 variant. All VIF frequencies (33.4–58.75 MHz) and sound trap bands (4.5–6.5 MHz) are fully functional within this constraint.

Does the TDA9885HN/V5 require an external crystal oscillator?

No, the TDA9885HN/V5 does not require an external crystal oscillator. Pin REF accepts either a 4 MHz external reference signal or drives a 4 MHz crystal directly as a 1-pin oscillator - eliminating the need for discrete oscillator components and reducing bill-of-materials count in TV and STB designs.

How is the sound carrier trap configured on the TDA9885HN/V5?

The TDA9885HN/V5 integrates four factory-trimmed sound carrier traps (4.5 MHz, 5.5 MHz, 6.0 MHz, 6.5 MHz) controlled automatically by the FM-PLL oscillator. Configuration is handled internally - no external components or I²C writes are needed beyond selecting the target TV standard during initialization, which triggers the appropriate trap activation.

What is the function of pin SIOMAD on the TDA9885HN/V5?

Pin SIOMAD on the TDA9885HN/V5 serves two functions: it outputs the sound intercarrier signal (140 mV rms) and selects the I²C module address (MAD) via external resistor networks. This dual-role pin reduces external component count and enables flexible bus addressing without dedicated address pins - a key feature for multi-device consumer AV systems.

Can the TDA9885HN/V5 operate with a 4.5 V supply voltage?

Yes, the TDA9885HN/V5 operates across 4.5 V to 5.5 V, with typical performance specified at 5.0 V. At 4.5 V, video and sound parameters (e.g., SNR, bandwidth, output level) may decrease slightly per datasheet Note [1], but full functionality including I²C communication, AGC, and PLL lock remains guaranteed - enabling compatibility with marginally regulated 5 V rails.
