VHF/ UHF-Tuner-IC

Description

This tuner IC requires a power supply of 5 V and performs This tuner IC is decigned for high performance tuners for

the function of three separate oscillators an mixers, TV, VCR and PCs.

SAWF-driver, L.O.-output and tri-state band switch.

Features

5 V supply voltage

Balanced L. O.-outputs for prescalers or PLL

SAW filter driver with low impedance output

Voltage regulator for stable operating characteristics

Frequency range from 48 to 860 MHz

Band A: balanced high impedance mixer input and

amplitude controlled oscillator

Band B + C: balanced low impedance mixer input and

symmetrical oscillator

ESD protection on all pins except oscillator pins and

RF-inputs

Benefits

The integration of 3 bands and the small SSO28

package allows to design very small and economical

3-band tuners with high performance.
