CY2077FSXC

CY2077 is an EPROM-programmable, high-accuracy, general-purpose, PLL-based design for use in applications such as modems, disk drives, CD-ROM drives, video CD players, DVD players, games, set-top boxes, and data/telecommunications. CY2077 can generate a clock output up to 133 MHz at 5 V or 100 MHz at 3.3 V. It has been designed to give the customer a very accurate and stable clock frequency with little to zero PPM error. CY2077 contains a 12-bit feedback counter divider and 10-bit reference counter divider to obtain a very high resolution to meet the needs of stringent design specifications. Furthermore, there are eight output divide options of /1, /2, /4, /8, /16, /32, /64, and /128. The output divider can select between the PLL and crystal oscillator output/external clock, providing a total of 16 different options to add more flexibility in designs. TTL or CMOS duty cycles can be selected.
