描述 Description

The SY89208V is a 3.3V/5V precision high-speed 2:1 multiplexer. It is functionally equivalent to the SY100EP58V but in an ultra-small 8-lead MLF??package that features a 70% smaller footprint. The signal-path inputs (Da and Db) are single-ended PECL/ECL compatible, and can accept a signal swing as low as 150mV. All I/O pins are 10k/100k EP ECL/PECL compatible.AC-performance is guaranteed over the industrial -40°C to +85°C temperature range and 3.0V to 5.5V supply voltage range. Maximum throughput (fMAX) is guaranteed to be 3GHz with a differential output swing ≥400mV. In addition, these multiplexers are optimized for low-jitter applications. The SY89208V is designed to operate in either ECL/PECL or PECL/LVPECL mode. The SY89208V is internally temperature compensated, thus is 100k EP ECL/PECL compatible--I/O logic levels remain constant over temperature.The SY89208V is part of Micrel's high-speed, Precision Edge??timing and distribution family. For applications that require a differential I/O combination, choose from a comprehensive product line of high-speed, low skew fanout buffers, translators, and clock dividers.

簡介

SY89208V屬于集成電路（IC）的信號開關多路復用器解碼器。由制造生產的SY89208V信號開關，多路復用器，解碼器邏輯型信號開關、多路復用器和編碼器 IC 可用于對以數字格式表示數據的電信號進行路由和選擇。這些器件與設計用于模擬信號的類似產品有所不同，它們保留的信息表示為兩個電狀態(tài)之一，而不是兩個外部界限內的無窮變化量。
