NXP Semiconductors TDA9887TS/V4,118

Overview

TDA9887TS/V4,118 from NXP Semiconductors (formerly Philips Semiconductors) is an I²C-controlled multistandard alignment-free IF-PLL demodulator IC for TV and STB applications, integrating VIF-PLL, SIF-PLL, FM radio demodulation, sound carrier traps (4.5–6.5 MHz), and a 5 V supply interface. It supports PAL/SECAM/NTSC standards with digital acquisition help across six VIF frequencies (33.4–58.75 MHz) and delivers 2 V_p-p composite video output at CVBS.

For engineers reviewing the TDA9887TS/V4,118 datasheet, TDA9887TS/V4,118 pinout, TDA9887TS/V4,118 application, or TDA9887TS/V4,118 equivalent, key selection criteria include its SSOP24 package, I²C programmable AFC and TOP settings, integrated FM-PLL for 10.7 MHz radio IF, multistandard synchronous demodulation linearity, and dual-mode QSS/intercarrier SIF processing.

Technical Context

The TDA9887TS/V4,118 implements two independent PLL systems: a vision IF-PLL with digitally assisted frequency acquisition and a narrow-band FM-PLL for radio/TV sound, both using low-radiation relaxation oscillators. Its VIF amplifier provides 66 dB gain control range via emitter degeneration, while the SIF path supports switchable QSS and intercarrier modes via I²C.

Functional integration includes a single-reference QSS mixer generating 2nd intercarrier signals, fully digital 4-bit AFC detection with current output at pin AFC, and simultaneous support for AM/FM sound demodulation with 50 µs de-emphasis. The device uses internal voltage stabilization (3.55 V reference) and features four selectable I²C module addresses via MAD pin configuration.

FAQ

What is the primary function of the TDA9887TS/V4,118 in a TV signal chain?

The TDA9887TS/V4,118 serves as the core IF-PLL demodulator in analog TV receivers, performing synchronous vision and sound demodulation for PAL, SECAM, and NTSC standards. It processes VIF and SIF signals, integrates FM radio demodulation at 10.7 MHz, and delivers composite video (CVBS) and audio (AUD) outputs. Its alignment-free architecture eliminates manual tuning, and I²C control enables dynamic reconfiguration - making TDA9887TS/V4,118 essential for multistandard broadcast reception without hardware changes.

Does the TDA9887TS/V4,118 support SECAM standard demodulation?

Yes, the TDA9887TS/V4,118 explicitly supports SECAM-L standard demodulation as part of its multistandard capability, confirmed in Section 2 (General Description) and Table 17 of the datasheet. It implements gated phase detection for L and L-accent standards and provides full VIF-AGC and sound carrier trap functionality compatible with SECAM's positive modulation scheme. This makes TDA9887TS/V4,118 suitable for European and CIS-region TV designs requiring SECAM compliance alongside PAL and NTSC.

How does the digital acquisition help feature improve channel switching in the TDA9887TS/V4,118?

The digital acquisition help in the TDA9887TS/V4,118 uses a down-counter-based frequency monitoring circuit that detects whether the VCO is within the ±2.3 MHz lock-in window before enabling phase-lock. During channel change, it injects corrective current into the VIF-PLL loop filter until the VCO reaches the target frequency - preventing false locking and reducing acquisition time to <100 ms. This ensures reliable demodulation after rapid tuning, and TDA9887TS/V4,118 maintains this behavior across all six supported VIF frequencies without external intervention.

Can the TDA9887TS/V4,118 be used for FM radio reception without additional IF conversion stages?

Yes, the TDA9887TS/V4,118 supports direct FM radio reception via its radio mode: it accepts a first IF of 33.3 MHz (for non-NTSC) or 41.3 MHz (NTSC-M/N) at the SIF inputs, downconverts it to 10.7 MHz using the internal VIF-PLL VCO as a local oscillator, and feeds the result to the FM-PLL demodulator. No external mixer or IF filter is required - the SIF SAW filter serves dual purpose. This capability is documented in Section 8.15 and confirmed by the FMIN pin functionality, making TDA9887TS/V4,118 uniquely suited for combined TV/radio tuner designs.

What are the key differences between the TDA9887TS/V4,118 and the TDA9887T/V4 variant?

The TDA9887TS/V4,118 uses an SSOP24 package (SOT340-1, 5.3 mm body width), while the TDA9887T/V4 uses SO24 (SOT137-1, 7.5 mm body width). Both share identical electrical specifications, pin functions, and I²C register maps. The SSOP variant enables higher board density in space-constrained TV tuner modules. Pin numbering differs slightly (e.g., OP1 is pin 3 on TDA9887TS/V4,118 vs. pin 3 on TDA9887T/V4), but signal roles and thermal characteristics remain consistent - confirming TDA9887TS/V4,118 as a drop-in layout upgrade for compact designs.
