NXP Semiconductors TDA8263HN/C1,518

Overview

TDA8263HN/C1,518 from NXP Semiconductors (formerly Philips Semiconductors) is a fully integrated direct-conversion QPSK/8PSK satellite tuner IC for digital TV broadcasting front-ends. It operates from 950 MHz to 2175 MHz, delivers 55 dB AGC range with 0.7 dB/step linearity, integrates an LNA and LC-based VCO, and outputs differential I/Q baseband signals compliant with DVB-S, DVB-S2, and BS digital standards in satellite receiver systems.

For engineers reviewing the TDA8263HN/C1,518 datasheet, TDA8263HN/C1,518 pinout, TDA8263HN/C1,518 application, or TDA8263HN/C1,518 equivalent, this page provides verified RF gain distribution, I²C address selection logic, LO quadrature error (<5°), RMS input level detection, and 32-pin HVQFN package thermal performance data required for satellite tuner design validation and SDD interface integration.

Technical Context

The TDA8263HN/C1,518 implements a Zero-IF architecture with integrated LC VCO delivering in-phase and quadrature LO signals to dual mixers, eliminating external IF filtering. Its 15-bit programmable main divider and 3-bit reference divider support comparison frequencies from 125 kHz to 2 MHz, enabling precise LO synthesis across the full 950–2175 MHz band.

RF signal path includes a switchable LNA (bypassable via 20 dB attenuation), AGC-controlled variable-gain amplifier (55 dB range), and programmable 5th-order baseband filters (5–36 MHz cut-off). Baseband outputs (IP/IN/QP/QN) are differential, DC-coupled at 1.65 V, and support 550 mV_p-p output swing with <1 dB I/Q gain mismatch and <5° quadrature error.

FAQ

What is the operating frequency range of the TDA8263HN/C1,518?

The TDA8263HN/C1,518 operates from 950 MHz to 2175 MHz, covering all major satellite bands including European DVB-S, North American DBS, Japanese BS digital, and US SMA-TV standards. This full-range coverage is enabled by its integrated LC VCO and programmable PLL dividers, allowing a single part to serve global satellite receiver designs without hardware variants.

How does the TDA8263HN/C1,518 handle high-input signal levels?

The TDA8263HN/C1,518 handles high-input signal levels up to 0 dBm per channel using an I²C-controllable 20 dB RF attenuation mode that bypasses the LNA and inserts fixed attenuation. This mode is selected via the RFATT bit and maintains signal integrity while preventing mixer compression-critical for strong-signal DBS reception where LNB output can exceed −15 dBm.

Does the TDA8263HN/C1,518 support both QPSK and 8PSK demodulation?

Yes, the TDA8263HN/C1,518 supports both QPSK and 8PSK demodulation through its direct-conversion Zero-IF architecture. Its low I/Q mismatch (<1 dB gain, <5° phase), high linearity (+6 dBm IIP3), and programmable baseband filters (5–36 MHz) ensure clean baseband signal delivery to downstream demodulators for both modulation schemes, as confirmed in DVB-S2 and BS digital applications.

What is the purpose of the XTOUT pin on the TDA8263HN/C1,518?

The XTOUT pin on the TDA8263HN/C1,518 provides a buffered 16 MHz output derived from the internal crystal oscillator, enabling it to drive the clock input of an external satellite demodulator IC (e.g., TDA10086). This eliminates the need for a second crystal in the system, reducing BOM cost, PCB area, and timing skew between tuner and demodulator sections.

Can multiple TDA8263HN/C1,518 devices share the same I²C bus?

Yes, up to four TDA8263HN/C1,518 devices can share one I²C bus using the AS pin to select unique addresses (C0–C7). Applying specific voltages to AS (0 V, 0.25×VCC, 0.5×VCC, or VCC) configures distinct write/read addresses, enabling multi-tuner architectures such as dual-LNB PVR receivers without address collision or bus arbitration overhead.
