FEATURES:

DESCRIPTION:

• Three internal PLLs

The IDT5V9888 is a programmable clock generator intended for high

performancedata-communications,telecommunications,consumer,and

networking applications. There are three internal PLLs, each individually

programmable,allowingforthreeuniquenon-integer-relatedfrequencies.

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.

• Internal non-volatile EEPROM

• JTAG and FAST mode I²C serial interfaces

• Input Frequency Ranges: 1MHz to 400MHz

• Output Frequency Ranges: 4.9kHz to 500MHz

• Reference Crystal Input with programmable oscillator gain and

programmable linear load capacitance

− 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

TheIDT5V9888canbeprogrammedthroughtheuseoftheI²CorJTAG

interfaces. The programming interface enables the device to be pro-

grammedwhenitisinnormaloperationorwhatiscommonlyknownasin-

systemprogrammable. AninternalEEPROMallowstheusertosaveand

restore the configuration of the device without having to reprogram it on

power-up. JTAG boundary scan is also implemented.

• 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

• Programmable Slew Rate Control

• Programmable Loop Bandwidth Settings

• Programmable output inversion to reduce bimodal jitter

• Redundant clock inputs with glitchless auto and manual

switchover options

Each of the three PLLs has an 8-bit pre-scaler and a 12-bit feedback

divider. Thisallowstheusertogeneratethreeuniquenon-integer-related

frequencies. The PLL loop bandwidth is programmable to allow the user

totailorthePLLresponsetotheapplication. Forinstance,theusercantune

the PLL parameters to minimize jitter generation or to maximize jitter

attenuation. Spread spectrum generation and fractional divides are

allowed on two of the PLLs.

• JTAG Boundary Scan

• Individual output enable/disable

• Power-down mode

Thereare10-bitpostdividersonfiveofthesixoutputbanks. Twoofthe

six output banks are configurable to be LVTTL, LVPECL, or LVDS. The

otherfouroutputbanksareLVTTL. TheoutputsareconnectedtothePLLs

via the switch matrix. The switch matrix allows the user to route the PLL

outputstoanyoutputbank. Thisfeaturecanbeusedtosimplifyandoptimize

the board layout. In addition, each output's slew rate and enable/disable

function can be programmed.

• 3.3VVDD

• Available in TQFP and VFQFPN packages
