• Manufacturer Part Number: 5V49EE504NLGI8
• Description: EEPROM PROGRAMMABLE CLOCK GENERATOR
• Manufacturer: IDT [Integrated Device Technology]

AC Timing Electrical Characteristics
(Spread Spectrum Generation = OFF)
1.Practical lower frequency is determined by loop filter settings.
2.A slew rate of 2.75V/ns or greater should be selected for output frequencies of 100MHz or higher.
3.Jitter measured with clock outputs of 27 MHz, 48 MHz, 24.576 MHz, 74.25 MHz and 25 MHz.
4.Includes loading the configuration bits from EEPROM to PLL registers. It does not include EEPROM programming/write time.
5.Actual PLL lock time depends on the loop configuration.
