EEPROM PROGRAMMABLE CLOCK GENERATOR

Description

The IDT5V49EE904 is a programmable clock generator

intended for high performance data-communications,

telecommunications, consumer, and networking

applications. There are four internal PLLs, each individually

programmable, allowing for four 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 IDT5V49EE904 is in-system, programmable and can

be programmed through the use of I

C interface. An

internal EEPROM allows the user to save and restore the

configuration of the device without having to reprogram it on

power-up.

Each of the four PLLs has an 7-bit reference divider and a

12-bit feedback divider. This allows the user to generate

four unique non-integer-related frequencies. The PLL loop

bandwidth is programmable to allow the user to tailor the

PLL response to the application. For instance, the user can

tune the PLL parameters to minimize jitter generation or to

maximize jitter attenuation. Spread spectrum generation

and/or fractional divides are allowed on two of the PLLs.

There are a total of six 8-bit output dividers. The outputs are

connected to the PLLs via a switch matrix. The switch

matrix allows the user to route the PLL outputs to any

output bank. This feature can be used to simplify and

optimize the board layout. In addition, each output's slew

rate and enable/disable function is programmable.
