High voltage VCO tuning output
4 PNP ports
1 NPN port/ADC input
Power down mode
Internal LOW/MID/HIGH band switch
Lock-in flag
6 programmable reference divider ratios (24, 28, 32, 64, 80, 128)
4 programmable charge pump currents
The IC is suitable for PAL, NTSC, SECAM, DVB-C, DVB-T, T-DMB, DMB-TH, DAB,
ISDB-T, Open Cable and ATSC tuners. The focus is on digital terrestrial.
The AGC stage makes the tuner AGC independent of the Video-IF AGC.
