This tuner IC requires a power supply of 5 V and performs
the function of three separate oscillators an mixers,
SAWF-driver, L.O.-output and tri-state band switch.
This tuner IC is decigned for high performance tuners for
TV, VCR and PCs.
D 5 V supply voltage
D Frequency range from 48 to 860 MHz
D Band A: balanced high impedance mixer input and
amplitude controlled oscillator
D Band B + C: balanced low impedance mixer input and
D Balanced L. O.-outputs for prescalers or PLL
D SAW filter driver with low impedance output
D Voltage regulator for stable operating characteristics
D ESD protection on all pins except oscillator pins and
D The integration of 3 bands and the small SSO28
package allows to design very small and economical
3-band tuners with high performance.
