Infineon Technologies TUA 9001

Overview

TUA 9001 from Infineon Technologies is a CMOS Direct Conversion Receiver (DCR) IC for DVB-H/T and CMMB broadcast reception in mobile/portable devices. It supports quad-band RF input (170–240 MHz VHF, 470–890 MHz UHF, 1.45–1.49 GHz & 1.672 GHz L-band), integrates fractional-N PLL with fully embedded VCO and loop filter, delivers <18 mW power at 10% duty cycle in DVB-H mode, and features a programmable 7th-order Chebyshev channel filter for 5/6/7/8 MHz bandwidths.

For engineers reviewing the TUA 9001 datasheet, TUA 9001 pinout, TUA 9001 application, or TUA 9001 equivalent, key selection criteria include its single/dual-supply operation, 50 Ω RF input interface, external LNA support (e.g., BFR380), fast wake-up (<1 ms), and differential I/Q analog baseband output compatibility with demodulators such as TDA18271 or SI2168.

Technical Context

The TUA 9001 implements a zero-IF architecture with automatic DC offset compensation and wide-band RF AGC, enabling robust reception under dynamic signal conditions. Its fractional-N synthesizer supports crystal or external reference inputs from 16–38.4 MHz and achieves fast frequency switching via integrated loop filter and VCO.

It uses a diplexer-based front-end to share one antenna across VHF/UHF and L-bands, and includes dedicated gain control logic (AGC0/AGC1/EXTAGC) plus LDO-regulated 1.5 V supply for internal analog blocks. The fully differential I/Q outputs interface directly to baseband ADCs without external SAW filtering.

Equivalent & Alternatives

The following parts are listed as comparable options for similar DVB-H/T RF tuner applications.

Compared with SI2168-B30 and MAX2161ETM+, the TUA 9001 uniquely balances quad-band coverage, DVB-H-optimized power states, and discrete I/Q interface-making it the only choice for modular, low-power, multi-standard tuner designs requiring external demodulator control and antenna sharing.

FAQ

What supply voltages does the TUA 9001 support?

The TUA 9001 operates from either a single 3.3 V supply or dual supplies (3.3 V digital + 2.8 V RF). Its internal 1.5 V LDO powers analog blocks, and voltage selection is configured via the RXEN pin timing sequence during power-up. No external regulator is required for analog core operation.

Does the TUA 9001 require an external SAW filter?

No. The TUA 9001 integrates a programmable 7th-order Chebyshev channel filter that meets ETSI spectral mask requirements for 5, 6, 7, and 8 MHz DVB-T/H channels. This eliminates the need for external SAW filters, reducing BOM cost and PCB area by approximately 12 mm² per channel.

Which external LNAs are validated for use with the TUA 9001?

Infineon explicitly references the BFR380 NPN RF transistor as a validated external LNA for VHF/UHF bands. The AGC0/AGC1 outputs provide dual-voltage control compatible with BFR380 bias networks, and design files for this pairing are included in Infineon's TUA9001 Application Note AN321.

Can the TUA 9001 be used for ATSC or ISDB-T reception?

No. The TUA 9001 is specifically designed and characterized for DVB-H, DVB-T, and CMMB standards. Its channel filter bandwidths (5/6/7/8 MHz), AGC response profile, and PLL loop bandwidth are optimized for these standards only-not for 6 MHz ATSC or 6/7/8 MHz ISDB-T channel masks or modulation schemes.
