DESCRIPTION

The E225x and E235x Series Modulators are new PAL format modulators with the output frequency set by a PLL. These modulators provide direct Phase-Locked Loop tuning in- stead of the previous screwdriver setting, providing software flexibil- ity over output channel control. The output may be tuned over the PAL channel range of 21 ~ 69. These two new modulator series retain the common modulator mechanical footprint of previous designs. A variety of versions and options are available, as shown in the table. The PLL programming is provided by an I 2C serial bus interface. Modulation factors of 100% and 55% are available. Test and evaluation software is available upon request for pro- gramming the E225X and E235X modulator models.
