SY55857L数据手册集成电路（IC）的转换器电平移位器规格书PDF

描述 Description

The SY55857L is a fully differential, high-speed dual translator optimized to accept any logic standard from single-ended TTL/CMOS to differential LVDS, HSTL, or CML and translate it to LVPECL. Translation is guaranteed for speeds up to 2.5Gbps (2.5GHz toggle frequency). The SY55857L does not internally terminate its inputs, as different interfacing standards have different termination requirements.

特性 Features

• Input accepts virtually all logic standards:
• Single-ended: SSTL, TTL, CMOS
• Differential: LVDS, HSTL, CML
• Guaranteed AC parameters over temperature:
• fMAX > 2.5Gbps (2.5GHz toggle)
• tr / tf < 200ps
• Within-device skew < 50ps

• Propagation delay < 400ps
• Low power: 46mW/channel (typ)
• 3.0V to 3.6V power supply
• 100K LVPECL outputs
• Flow-through pinout and fully differential design
• Two channels in a 10-pin (3mm x 3mm) MSOP package

简介

SY55857L属于集成电路（IC）的转换器电平移位器。由制造生产的SY55857L转换器，电平移位器逻辑转换器或电平移位器 IC 可用于在数字逻辑设备之间传递信息，这些设备可在不同/不兼容的供电电压下工作，或可实现不同的信令方式。例如，可以将需要 5 V 电源的数字输出传感器连接到具有 3.3 V I/O 电源的 FPGA，或者在 CMOS 或 TTL 等单端信令方式与 PECL 或 LVDS 等差分技术之间进行转换。
