IDT5V2528/A

The IDT5V2528 inputs, PLL core, Y0, Y1, andFBOUT buffers operate from

the 3.3V VDD and AVDD power supply pins.

FEATURES:

• Operates at 3.3V VDD/AVDD and 2.5V/3.3V VDDQ

• 1:10 fanout

One bank of ten outputs provide low-skew, low-jitter copies of CLK. Of

the ten outputs, up to seven may be configured for 2.5V or 3.3V LVTTL

outputs. The number of 2.5V outputs is controlled by 3-level input signals

G_CtrlandT_Ctrl, andbyconnectingtheappropriateVDDQ pinsto2.5Vor

3.3V. The 3-level input signals may be hard-wired to high-mid-low levels.

When the G_Ctrl input is mid or high, the outputs switch in phase and

frequencywithCLK;whentheG_Ctrlislow, alloutputs(exceptFBOUT)are

disabledtothelogic-lowstate.

UnlikemanyproductscontainingPLLs,theIDT5V2528doesnotrequire

external RC networks. The loop filter for the PLL is included on-chip,

minimizing component count, board space, and cost.

Because it is based on PLL circuitry, the IDT5V2528 requires a

stabilization time to achieve phase lock of the feedback signal to the

referencesignal.Thisstabilizationtimeisrequired,followingpowerupand

• 3-level inputs for output control

• External feedback (FBIN) pin is used to synchronize the

outputs to the clock input signal

• No external RC network required for PLL loop stability

• Configurable 2.5V or 3.3V LVTTL outputs

• tPD Phase Error at 100MHz to 166MHz: ±150ps

• Jitter (peak-to-peak) at 133MHz and 166MHz: ±75ps

• Spread spectrum compatible

• Operating Frequency:

−

Std: 25MHz to 140MHz

A: 25MHz to 167MHz

−

• Available in TSSOP package

DESCRIPTION:

TheIDT5V2528isahighperformance, low-skew, low-jitter, phase-lock application of a fixed-frequency, fixed-phase signal at CLK, as well as

loop (PLL) clock driver. It uses a PLL to precisely align, in both frequency following any changes to the PLL reference or feedback signals. The PLL

and phase, the feedback (FBOUT) output to the clock (CLK) input signal. can be bypassed for test purposes by strapping AVDD to ground.
