DESCRIPTION:
The IDT5V9885 is a programmable clock generator intended for high performance data-communications, telecommunications, consumer, and networking applications. There are three internal PLLs, each individually programmable, allowing for three unique non-integer-related frequencies. The frequencies are generated from a single reference clock. The reference clock can come from one of the two redundant clock inputs. A glitchless automatic or manual switchover function allows any one of the redundant clocks to be selected during normal operation.
The IDT5V9885 can be programmed through the use of the I2C or JTAG interfaces. The programming interface enables the device to be programmed when it is in normal operation or what is commonly known as in system programmable. An internal EEPROM allows the user to save and restore the configuration of the device without having to reprogram it on power-up. JTAG boundary scan is also implemented.

FEATURES:
• Three internal PLLs
• Internal non-volatile EEPROM
• JTAG and FAST mode I2C serial interfaces

   − Crystal Frequency Range: 8MHz to 50MHz
• Each PLL has an 8-bit pre-scaler and a 12-bit feedback-divider
• 10-bit post-divider blocks
• Fractional Dividers
• Two of the PLLs support Spread Spectrum Generation capability
• I/O Standards:
   − Outputs - 3.3V LVTTL/ LVCMOS, LVPECL, and LVDS
   − Inputs - 3.3V LVTTL/ LVCMOS
