CY2077

High-accuracy EPROM Programmable

Single-PLL Clock Generator

Features

■ High-accuracy PLL with 12-bit multiplier and 10-bit divider

■ EPROM programmability

■ 3.3 V or 5 V operation

■ Operating frequency

❐ 390 kHz–133 MHz at 5 V

❐ 390 kHz–100 MHz at 3.3 V

■ Reference input from either a 10–30 MHz fundamental toned

crystal or a 1–75 MHz external clock

■ EPROM selectable TTL or CMOS duty cycle levels

■ Sixteen selectable post-divide options, using either PLL or

reference oscillator/external clock

■ Programmable PWR_DWN or OE pin, with asynchronous or

synchronous modes

■ Low jitter outputs typically

❐ 80 ps at 3.3 V/5 V

■ Controlled rise and fall times and output slew rate

■ Available in both commercial and industrial temperature ranges

■ Factory programmable device options
