3.3 VOLT ZERO DELAY CLOCK MULTIPLIER 1

IDT2308B REV B 030509

Description

The IDT2308B is a high-speed phase-lock loop (PLL) clock

multiplier. It is designed to address high-speed clock

distribution and multiplication applications. The zero delay

is achieved by aligning the phase between the incoming

clock and the output clock, operable within the range of 10

to 133 MHz.

The IDT2308B has two banks of four outputs each that are

controlled via two select addresses. By proper selection of

input addresses, both banks can be put in tri-state mode. In

test mode, the PLL is turned off, and the input clock directly

drives the outputs for system testing purposes. In the

absence of an input clock, the IDT2308B enters power

down, and the outputs are tri-stated. In this mode, the

device will draw less than 25µA.

The IDT2308B is available in six unique configurations for

both prescaling and multiplication of the Input REF Clock.

(see Available Options table.)

The PLL is closed externally to provide more flexibility by

allowing the user to control the delay between the input

clock and the outputs.

Features

•Phase-Lock Loop Clock Distribution for Applications

ranging from 10 MHz to 133 MHz operating frequency

•Distributes one clock input to two banks of four outputs

•Separate output enable for each output bank

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

outputs to the clock input

•Output Skew <200 ps

•Low jitter <200 ps cycle-to-cycle

•1x, 2x, 4x output options (see Available Options table)

•No external RC network required

•Operates at 3.3 V VDD

•Available in 16-pin SOIC and TSSOP packages

•Available in Commercial and Industrial temperature

ranges

Note 1: Output phase is indeterminant (0° or 180° from input clock).

Absolute Maximum Ratings1

Notes:

1. Stresses above the ratings listed below can cause permanent damage to the IDT2308B. These ratings, which are standard

values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other

conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute

maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over

the recommended operating temperature range.

2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

3. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750

mils.

Zero Delay and Skew Control

To close the feedback loop of the IDT2308B, the FBK pin can be driven from any of the eight available output pins.

The output driving the FBK pin will be driving a total load of 7 pF plus any additional load that it drives. The relative

loading of this output (with respect to the remaining outputs) can adjust the input-output delay.

For applications requiring zero input-output delay, all outputs including the one providing feedback should be

equally loaded. If input-output delay adjustments are required, use the Output Load Difference Chart to calculate

loading differences between the feedback output and remaining outputs. Ensure the outputs are loaded equally, for

zero output-output skew.
