NXP Semiconductors TDA8263HN/C1,118

Overview

TDA8263HN/C1,118 from NXP Semiconductors (formerly Philips Semiconductors) is a fully integrated direct-conversion QPSK/8PSK satellite tuner IC for digital TV broadcast front-ends. It operates from 950 MHz to 2175 MHz, delivers 55 dB AGC range with <0.7 dB/step linearity using an 8-bit DAC, integrates a low-noise LNA (NF = 8 dB), and provides programmable 5–36 MHz 5th-order baseband filters for I/Q paths - enabling direct interface to SDDs like TDA10086 in DBS/DVB-S/S2 receivers.

For engineers reviewing the TDA8263HN/C1,118 datasheet, TDA8263HN/C1,118 pinout, TDA8263HN/C1,118 application, or TDA8263HN/C1,118 equivalent, key selection criteria include its ZIF architecture eliminating IF filtering, I²C-configurable LO synthesizer with ±5° quadrature error, RMS RF input level detection, four selectable I²C addresses, and thermal-enhanced HVQFN32 package supporting high-density satellite receiver designs.

Technical Context

The TDA8263HN/C1,118 implements a zero-IF (ZIF) architecture with integrated LC VCO, dual mixers, and baseband amplifiers delivering differential I/Q outputs. Its PLL synthesizer uses a 15-bit main divider and programmable reference divider (125 kHz–2 MHz comparison frequency) to achieve precise LO tuning across the full 950–2175 MHz band.

RF signal path includes a switchable LNA/attenuator (0 dB or −20 dB mode), AGC-controlled variable gain amplifier (−14 dB to +67 dB), and on-chip RMS level detector readable via I²C. Baseband section features digitally controlled 5–36 MHz LPF cutoff (32 steps) and 0–9 dB programmable output gain, optimized for QPSK/8PSK demodulation at symbol rates up to 45 MBd.

FAQ

What is the operating frequency range of the TDA8263HN/C1,118?

The TDA8263HN/C1,118 operates from 950 MHz to 2175 MHz, covering all major satellite bands including DVB-S (Europe), DBS (North America), BS Digital (Japan), and SMA-TV (US). This range supports both QPSK and 8PSK modulation schemes used in current and next-generation satellite broadcast standards.

Does the TDA8263HN/C1,118 support 8PSK demodulation?

Yes, the TDA8263HN/C1,118 is explicitly designed for both QPSK and 8PSK demodulation as stated in its general description and applications list. Its low phase noise (−94 dBc/Hz @ 100 kHz), <5° quadrature error, and high linearity (IIP3 = +6 dBm) ensure clean I/Q signal delivery required for 8PSK constellation fidelity in DVB-S2 and BS Digital systems.

How does the AGC function work on the TDA8263HN/C1,118?

The TDA8263HN/C1,118 uses an analog AGC input (pin AGC) accepting 0.3–3 V to control RF gain over a 55–60 dB range with <0.7 dB/step linearity when paired with an 8-bit DAC. Gain is adjusted dynamically by the downstream Satellite Demodulator and Decoder (SDD), enabling closed-loop signal optimization for varying LNB output levels.

What package type is used for the TDA8263HN/C1,118?

The TDA8263HN/C1,118 is housed in an HVQFN32 (SOT617-1) package: a 5 × 5 × 0.85 mm plastic thermal-enhanced very thin quad flat package with 32 terminals and an exposed die pad. Its 43 K/W junction-to-ambient thermal resistance supports reliable operation at +85°C ambient in compact set-top box enclosures.

Can multiple TDA8263HN/C1,118 devices share the same I²C bus?

Yes, the TDA8263HN/C1,118 supports four selectable I²C addresses via the AS pin voltage (0 V, 0.25×VCC, 0.5×VCC, or VCC), allowing up to four identical tuners on a single I²C bus. This enables dual-LNB, picture-in-picture, or multi-tuner PVR architectures without address collision or bus contention.

What is the purpose of the XTOUT pin on the TDA8263HN/C1,118?

The XTOUT pin delivers a buffered 16 MHz clock signal derived from the crystal oscillator (XT/XTN pins). This output can directly drive the crystal input of companion demodulator ICs (e.g., TDA10086), eliminating the need for a second crystal and reducing BOM cost and board space in satellite receiver designs.
