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 - 20C Tamb
80;
- used frequency channels correspond to
european standards with the following radio-
frequency 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.
