RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT2064 SINGLE-CHIP BROADBAND TUNER PRODUCT BRIEF The MT2064 is a low-power 3.3V singlechip broadband tuner with an integrated PRELIMINARY IF variable-gain amplifier. MT2064 Single-Chip Broadband Tuner The MicroTuner™ MT2064 is an advanced, low-power single-chip broadband tuner that has been optimized for high-performance cable modems and embedded multimedia terminal adapter (E-MTA) that require low composite distortion and low noise under digital cable environments. The MT2064 is capable of receiving frequencies in the 48 MHz to 1 GHz range and of converting a selected channel to a standard intermediate frequency (IF) between 30 MHz and 60 MHz. The MT2064’s low phase noise makes it ideal for use in digital applications such as video, voice and high-speed data. Its dualconversion architecture, with no requirement for tracking filters, yields the desirable characteristics of traditional cable television tuners: controlled input impedance across the entire input band, low in-band emissions, and outstanding image rejection. In addition, the MT2064 provides excellent in-band flatness as well as very repeatable gain characteristics across the complete reception band. The MT2064’s low-power consumption significantly conserves current and can be effectively used to extend the operation of batterypowered E-MTA. The MT2064 can be used in conjunction with Microtune’s upstream amplifiers to create a complete RF front end for bidirectional cable modem APPLICATIONS • • • VoIP Telephony Modems Cable Modems PacketCable™ E-MTA FEATURES • • • • • • • • • • • • • • 48 MHz to 1000 MHz input frequency range 3.3V power supply Single-ended RF input reduces BOM by eliminating input balun Works seamlessly with all digital demodulators Low power dual-conversion architecture Minimal external components No tunable parts required Integrated IF variable gain amplifier for direct connection to digital demodulators Low phase noise for excellent performance in QAM 64 and QAM 256 systems Software and hardware shutdown modes Frequency synthesizers fully programmable via serial-control interface Fully integrated VCO circuitry simplifies PCB layout General-purpose input/ output (GPIO) controllable via serialcontrol interface Intermediate frequency (IF) output ® • • • fully compatible with DOCSIS 2.0, EuroDOCSIS™ 2.0 Integrated temperature sensor Operates with a 16 MHz crystal Small 6 mm x 6 mm 40-pin Quad Flat No-Lead (QFN) package MT2064 SINGL E-C HIP BRO ADB AND TU N ER PRODUCT BRIEF TUNER ELECTRICAL CHARACTERISTICS RECOMMENDED OPERATING CONDITIONS PARAMETER Supply voltage MIN TYP MAX UNIT 3.15 3.3 3.45 V 25 mVp-p Supply voltage ripple Operating junction temperature 125 °C Serial control clock 400 kHz ABSOLUTE MAXIMUM RATINGS PARAMETER MIN Supply voltage Storage temperature range 3.6 V °C 260 °C VCC +0.3 V RFIN RFCAP NC UPCVCC UPCVCC DNCVCC DNCP DNCN GND VGAINP 40 39 38 37 36 35 34 33 32 31 30 VGAINN NC 2 29 VGAVCC NC 3 28 VGAOUTP LO1AVCC 4 27 VGAOUTN NC 5 26 IFAGC LO1REG 6 25 LO2AVCC LO1T1 7 24 LO2REG 15 16 17 18 19 20 SERDATA SERCLK SERADDR GPIO LO2DVCC LO2LPF VCC 21 14 10 SRON LO2TP LO1LPF 13 LO2TN 22 SROP 23 9 12 8 11 LO1T2P LO1T2N NC TYP MAX UNIT Power supply Active current 242 mA RF signal path Input frequency range 48 1000 MHz Second intermediate frequency (programmable) 30 60 MHz Noise figure 9.5 dB RF gain range 33 dB Image rejection 65 dBc Phase noise (10 kHz) -84 dBc/Hz Phase noise (100 kHz) -106 dBc/Hz Output voltage 2.0 Vp-p AGC range 37 dB IF Variable Gain Amplifier (VGA) PARAMETER 1 Exposed paddle on package bottom MIN SECOND IF SAW ELECTRICAL CHARACTERISTICS UPCVCC LO1DVCC PRELIMINARY -0.3 UNIT 150 -40 Lead-free temperature (soldering 5 seconds) Input voltage MAX PARAMETER MIN TYP Second IF SAW loss MAX UNIT 17 dB SIF RFin ATN UPC FIFF DNC VGA SIF RFPM LO1 IFAGC IFPM FCU LO2 GCU MT2064 Pin Diagram SER CLK Data SRO GPIO 16 MHz MT2064 Block Diagram Microtune, Inc., 2201 Tenth Street, Plano, TX 75074, USA Tel: +1-972-673-1600, Fax: +1-972-673-1602, E-mail: [email protected], Web site: www.microtune.com For a detailed list of office locations, sales offices, and sales representatives, visit our Web site at www.microtune.com The information in this document is believed to be accurate and reliable.
