TDA9889TS/V1,512

Overview

The TDA9889TS is a DVB selective AGC amplifier with integrated selectivity, designed for terrestrial and cable TV reception. It provides downconversion and filtering without alignment for all DVB standards. The device features a 70 dB variable gain wide-band IF amplifier (AC-coupled) and a synthesizer-controlled oscillator for frequencies of 31, 31.5, 32, 40, and 53 MHz. It delivers a 2 V (p-p) differential low IF output for direct ADC interfacing. Operating voltage is 4.5 to 5.5 V with a typical supply current of 55 mA. It includes an integrated anti-aliasing tracking low-pass filter and ESD protection.

Feature Summary

• Integrates a variable gain wide-band IF amplifier with external control voltage input.
• Provides digital video broadcast downconversion with integrated selectivity to reduce external component requirements.
• Includes a fully integrated synthesizer-controlled oscillator with excellent phase noise performance.
• Features a tuner automatic gain control detector with peak-sync detection capabilities.

Applications

• Terrestrial TV reception systems
• Cable TV reception systems
• Digital Video Broadcast (DVB) set-top boxes

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary environmental specifications for the intended operating temperature range. Ensure compatibility with existing reference clock sources and logic levels for standard selection switches.

Selection Notes

Select this component for applications requiring integrated DVB downconversion and filtering. Consider the specific region's channel bandwidth and center frequency requirements when configuring the logic switches. Evaluate the need for external tuner AGC integration based on the hybrid application mode settings available via the S2 pin.

Part Context

This part belongs to the TDA9888TS/TDA9889TS family of DVB selective AGC amplifiers. It is manufactured by NXP Semiconductors (formerly Philips Semiconductors). The device is housed in a plastic shrink small outline package with 16 leads (SSOP16/SOT338-1). It serves as a key interface between the tuner and the channel decoder in modern television receivers.

Replacement Considerations

TDA9888TS is the primary functional substitute within the same product specification document, sharing identical core architecture but differing in standard switch configurations for specific regional standards.
