LTC6957的产品详情:

LTC6957-1 / LTC6957-2 / LTC6957-3 / LTC6957-4 是一个非常低相位噪声、双输出 AC 信号缓冲器 / 驱动器 / 逻辑电平转换器系列。输入信号可以是一个正弦波或任何逻辑电平 (≤ 2VP-P)。该系列包括以下 4 个具有不同输出逻辑信号类型的成员:

LTC6957-1:LVPECL 逻辑输出

  LTC6957-2:LVDS 逻辑输出

LTC6957-3:CMOS 逻辑,同相输出

LTC6957-4:CMOS 逻辑,互补型输出

LTC6957 将以极低的附加噪声进行任何逻辑信号的缓冲和分配,不过,在把正弦波信号转换为逻辑电平方面,该器件相比于同类产品确实更胜一筹。初始放大级具有可选的低通滤波,以较大限度地抑制噪声,同时仍然对信号实施放大以增加其摆率。当采用缓慢摆率的输入信号 (例如:一个典型的 10MHz 正弦波系统基准) 时,该输入级滤波 / 噪声限制特别有助于提供相位噪声尽可能低的信号。


应用

  • 系统基准频率分配
  • 高速 ADC、DAC、DDS 时钟驱动器
  • 军事和安全无线电
  • 低噪声定时触发器

LTC6957的评估套件:

AD-SYNCHRONA14-EBZ:Multichannel System Clocking Device

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.

The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.

With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.

APPLICATIONS

High accuracy reference clock distribution Systems clocked from a single source Clocks derived from 100MHz or 122.88MHz Phased Array Systems, RADAR, EW, SATCOMS, SDR Bench Equipment Remote controlled operation
