EEPROM PROGRAMMABLE CLOCK GENERATOR

5V49EE502

Description

Features

The 5V49EE502 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. Automatic or manual

switchover function allows any one of the redundant clocks

to be selected during normal operation.

• Four internal PLLs

• Internal non-volatile EEPROM

• Fast (400kHz) mode I C serial interface

• Input frequency range: 1MHz to 200MHz

• Output frequency range: 4.9kHz to 500MHz

• Reference crystal input with programmable linear load

capacitance

— Crystal frequency range: 8MHz to 50MHz

The 5V49EE502 is in-system, programmable and can be

• Two independently controlled VDDO (1.8V to 3.3V)

programmed through the use of I C interface. An internal

• Each PLL has a 7-bit reference divider and a 12-bit

feedback-divider

EEPROM allows the user to save and restore the

configuration of the device without having to reprogram it on

power-up.

• 8-bit output-divider blocks

• Fractional division capability on one PLL

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.

• Two of the PLLs support spread spectrum generation

capability

• I/O standards:

— Outputs: 1.8V to 3.3 V LVTTL/ LVCMOS

— Outputs: LVPECL, LVDS and HCSL

— Inputs: 3.3 V LVTTL/ LVCMOS

• Programmable slew rate control

• Programmable loop bandwidth

There are a total of four 8-bit output dividers. Each output

bank can be configured to support LVTTL, LVPECL, LVDS

or HCSL logic levels. Out0 (Output 0) supports 3.3V

single-ended standard only. 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

• Programmable output inversion to reduce bimodal jitter

• Redundant clock inputs with auto and manual switchover

options

• Individual output enable/disable

• Power-down mode

enable/disable function is programmable.

• 3.3V core V

• Available in 24-QFN package

• -40° to +85°C industrial temperature operation
