DESCRIPTION:
The IDT5V9885C 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.

FEATURES:
• Three internal PLLs
• Internal non-volatile EEPROM

   − 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
