Abilis programmable RF modulators, offered in an industry-standard 16-pin SOIC RoHS/Lead(Pb)-free package, are designed for use in Set-Top Boxes and similar applications. They use a high speed I2C interface to support PAL, SECAM or NTSC standards. They are the latest generation of the legacy MC44BS37x family of devices from Freescale Semiconductor.
These RF modulators are now available in a new product family: AS44CE37x. This AS44CE37x latest version is 100% hardware (pin to pin) and software compatible with the previous version of product family (AS44CC37x). The full compatibility insures that no changes are required in existing AS44CC37x customer designs (layout and PCB).
AS44CE37x offers additional features and better optimized performance, such as supporting 4 MHz and 16 MHz external crystals, external clock signal capabilities, less noise susceptibility, and better sound PLL robustness.
