RF Modulator

Description

RF modulator for terrestrial receivers PACOSTAR PST 6060 and STRONG SRT8113

If  don't have I2C control, Modulator is working on 471.25MHz channel
Supports multiple TV system: NTSC,PAL,SECAM(B/G,I, D/K, L, M/N)
Can be adjusted via the I2C output RF signal amplitude (70~80dBuV)
adjustable VIDEO through I2C, AUDIO input attenuation
can be selected via I2C output frequency: 46MHz ~ 880MHz
can be controlled via I2C loop-through switch
low-power standby mode, the circuit loss is only 5mA (TYP.)
-chip LDO, support from 3.3V ~ 5.0V power supply, current consumption 85mA
