| M I C R O T U N ETM 404X SERIES RF TUNER MODULES MIXED DIGITAL AND ANALOG TV APPLICATIONS APPLICATIONS * * * Set-top boxes TV Sets PC TV Boards FEATURES * * * * * * Frequency range: 50 MHz to 860 MHz NTSC and ATSC compatible Integrated IF demodulator for analog video and audio Baseband outputs for analog video and audio Balanced IF output for digital applications Improved adjacent channel performance for ATSC reception All functions controlled by I C bus 2 Modules can be implemented with different sockets, filters, interfaces, connectors, and other customizable options within the same pinouts. * * * * * The 404X Series RF Tuner Module is specifically designed for mixed digital and analog TV reception. This device combines the functions of both an analog multimedia front end and a digital tuner in a single unit. For reception of digitally modulated signals, a balanced IF output has a center frequency of 44 MHz. The IF outputs connect directly with an applicable external SAW filter. An AGC control input allows for external control of the output signal amplitude. This tuner covers a frequency range of 50 MHz to 860 MHz with a channel bandwidth of 6 MHz. The module's hyperband tuner for analog TV reception covers the frequency range of 50 MHz to 860 MHz and contains an IF part with SAW filter, IF amplifier, and video and sound demodulators. The AF and CVBS signals are available at the audio and video output pins. A video buffer is built in for direct connection to a 75 input. For both digital and analog applications, the reception frequency range is divided into VHF low, VHF high, and UHF. Band selection and tuning are done completely via the IC-bus. In addition, the AFC voltage generated by the IF demodulator is fed to an integrated A/D converter in the PLL IC and is readable via the IC bus. A digital AFC function can be implemented. A DC/DC converter for 33V generation is built in, so that only a single supply voltage of 5V is required. TTL-Controlled switchable antenna inputs Low noise figure AFC byte readable through I C bus 2 Single 5V supply Product Brief 404X SERIES RF TUNER MODULES PRODUCT BRIEF FUNCTIONAL CHARACTERISTICS PARAMETER Frequency range for digital reception VHF Low VHF High UHF Frequency range for analog reception VHF Low (ch 02 to G) VHF High (ch H to W+26) UHF (ch W+27 to 69) Recommended take-over frequency VHF Low / VHF High UHF IF Frequency Digital modulation (center) Picture carrier Sound carrier Input impedance VHF/UHF Common IF Output Operating temperature Storage temperature Supply voltage MIXED DIGITAL AND ANALOG TV APPLICATIONS MEASUREMENT 57 to 160 165 to 454 459 to 858 55.25 to 157.25 163.25 to 451.25 457.25 to 801.25 162 457 44 45.75 41.25 75 75 0 to +60 -25 to +60 5 UNIT MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz MHz , Unbalanced , Balanced C C V 4040 FI5 4041 FI5 4042 FI5 404X Series Tuner Modules TUNER MODULE DATA PARAMETER Voltage gain (80 MHz to 862 MHz) Ch 02 to ch W+26 1 kHz Distance from carrier Noise figure Phase noise 1 kHz Distance from carrier VHF Low VHF High UHF 10 kHz Distance from carrier VHF Low VHF High UHF 100 kHz Distance from carrier VHF Low VHF High UHF VSWR (Antenna input) AGC Range VHF Low VHF High UHF IF Rejection VHF Low VHF High UHF Image rejection VHF Low VHF High (ch H to ch 13) VHF High (ch J to ch W+29) UHF RF Tilt RF Input level 1 dB Compression point VHF Low VHF High UHF CSO / CTB / IP3 Composite triple beat Composite second order beat IP3 (Two tone) MIN 38 36 TYP 43 40 7 MAX UNIT dB dB dB 9 VIDEO OUTPUT PARAMETER CVBS Output level Load impedance Video S/N: VHF UHF Noise limiting sensitivity for video S/N Frequency response 1 MHz 2 MHz 3 MHz 3.58 MHz Differential gain Differential phase C/L Gain C/L Delay -68 -60 -57 -95 -85 -85 -110 -106 -103 2 45 40 35 50 60 60 60 60 50 45 45 80 80 80 85 82 84 2 60 50 50 -60 -55 -55 -80 -80 -80 -100 -100 -100 4 dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz dBc/Hz MIN 0.8 TYP 1 75 46 45 MAX 1.2 UNIT Vp-p dB dB dBV dB dB dB dB %p-p p-p % ns 45 -1.5 -2 -4 -8 3 1.5 2 2 -1 10 5 20 50 dB dB dB dB dB dB dB dB dB dB dB dBV dBV dBV dBV >60 >60 >85 dB dB dBV -50 -100 -15 -25 AUDIO OUTPUT PARAMETER Output level: Output resistance Load impedance AF Level THD+N S/N Frequency response 40 Hz to 15 kHz AC DC MIN 2.1 2.2 370 TYP 1.3 2.5 200 460 49 MAX 2.9 UNIT Vp-p V k mV rms % dB dB 2.5 110 550 0.5 -1 1 2ND IF OUTPUT PARAMETER AC Level of 4.5 MHz Load impedance MIN 50 0.5 TYP 120 MAX UNIT mVp-p World Headquarters * Microtune, Inc., 2201 Tenth Street, Plano, TX 75074 * Tel: 972-673-1600, Fax: 972-673-1602, E-mail: sales@microtune.com, Web site: www.microtune.com European Headquarters * Microtune GmbH and Co.
