ILA5737D Low-power high-frequency triple (metric waves, microwaves) mixer-oscillator for video equipment IC ILA5737D is monolithic microcircuit, low-power high-frequency triple (metric waves, microwaves) mixer-oscillator for video equipment used in TV tuners and videotape recorder tuners. IC does assignment, matching, filtration and amplification of IF from TV signal applied from on-air within three tunable frequency ranges. Functions does assignment and amplification of IF from TV signal applied from on-air within three tunable frequency ranges. Features. Implemented in plastic small-size 24-pin SSOP-case with external lead pitch 0,65mm; - supply voltage 4.5 to 5.5V; - consumption current 42 to 58 mkA; - operation temperature range - 20ºC ≤ Tamb ≤ 80ºС; - used frequency channels correspond to european standards with the following radiofrequency ranges: 48.25 MHz to 168.25 MHz; 175.25 MHz to 447.25 MHz; 455.25 MHz to 855.25 MHz - when using the corresponding external interconnection circuit, they are suitable for construction of all-channel tuners NTSC (USA and Japan). - allows the designer to make economic and small-size 3-bands tuner; Using ILA5737D time of tuner fabrication may be considerably reduced. Temperature compensation of reference voltage.
