AD9551/PCBZ开发板套件编程器的评估演示板及套件规格书PDF中文资料

AD9551/PCBZ属于开发板套件编程器的评估演示板及套件。由亚德诺半导体技术有限公司制造生产的AD9551/PCBZ评估和演示板及套件该系列产品提供了一种方便的方法，在经过验证的实施环境中评估某些重点器件的性能或特性。评估方法通常有完善的文档说明，并且视乎具体情况由评估软件提供支持。产品通常由印刷电路板组成，板上已装有重点器件以及必要或有用的支持元器件，另外也可能包括其他组件，例如电缆或电源。对于数量特别多或类别独特的器件类别(如 ADC、DAC 和开关模式电源)，评估平台可组合为一个单独的产品系列。

GENERAL DESCRIPTION

The AD9551 accepts one or two reference input signals to synthesize one or two output signals. The AD9551 uses a fractional-N PLL that precisely translates the reference frequency to the desired output frequency. The input receivers and output drivers provide both single-ended and differential operation.

FEATURES

Translation between any two standard network rates

Dual reference inputs and dual clock outputs

Pin programmable for standard network rate translation

SPI programmable for arbitrary rational rate translation

Output frequencies from 10 MHz to 900 MHz

Input frequencies from 19.44 MHz to 806 MHz

On-chip VCO

Meets OC-192 high band jitter generation requirement

Supports standard forward error correction (FEC) rates

Supports holdover operation

Supports hitless switchover and phase build-out (even with

unequal reference frequencies)

SPI-compatible 3-wire programming interface

Single supply (3.3 V)

APPLICATIONS

Multiservice switches

Multiservice routers

Exact network clock frequency translation

General-purpose frequency translation
