HMC674LC3CTR集成電路（IC）的比較器規(guī)格書(shū)PDF中文資料

HMC674LC3CTR屬于集成電路（IC）的比較器。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的HMC674LC3CTR比較器邏輯比較器系列產(chǎn)品用于根據(jù)以數(shù)字格式表示的信息比較結(jié)果來(lái)生成輸出；身份型比較器指示兩個(gè)輸入是否相同，幅度型比較器還指示兩個(gè)輸入不相同時(shí)哪個(gè)較大。它們不同于比較兩個(gè)模擬輸入幅度的器件，后者稱(chēng)為線性比較器且單獨(dú)分類(lèi)。

GENERAL DESCRIPTION

The HMC674LC3C/HMC674LP3E are silicon germanium (SiGe), monolithic, ultrafast comparators that feature reduced swing positive emitter-coupled logic (RSPECL) output drivers and latch inputs. These comparators support 10 Gbps operation and provide 85 ps propagation delay and an input signal minimum pulse width of 60 ps with 0.2 ps rms of random jitter (RJ). Overdrive and slew rate dispersion is typically 10 ps, making the HMC674LC3C/HMC674LP3E ideal for a wide range of applications from ATE to broadband communications. The RSPECL output stages directly drive 400 mV into a 50 ? resistor terminated to VTT = (VCCO ? 2.0 V), where VTT is the PECL termination voltage (see Figure 16). The HMC674LC3C/HMC674LP3E feature a high speed latch and programmable hysteresis. These devices can operate in either latch mode or as a tracking comparator.
