     3.3 V ECL Programmable Delay Chip

    产品信息

    The MC100EP195B is a Programmable Delay Chip (PDC) designed primarily for clock deskewing and timing adjustment. It provides variable delay of a differential NECL/PECL input transition. Thedelay section consists of a programmable matrix of gates and multiplexers as shown in the logic diagram, Figure 2. The delay increment of the EP195B has a digitally selectable resolution of about 10 ps and a net range of up to 10.2 ns. The required delay is selected by the 10 data select inputs D(9:0) values and controlled by the LEN (pin 10). A LOW level on LEN allows a transparent LOAD mode of real time delay values by D(9:0). A LOW to HIGH transition on LEN will LOCK and HOLD currentvalues present against any subsequent changes in D(10:0). The approximate delay values for varying tap numbers correlating to D0 (LSB) through D9 (MSB) are shown in Table 6 and Figure 3.
    • Maximum Input Clock Frequency >1.2 GHz Typical
    • Programmable Range: 0 ns to 10 ns
    • Delay Range: 2.2 ns to 12.2 ns
    • 10 ps Increments
    • PECL Mode Operating Range:VCC = 3.0 V to 3.6 V with VEE = 0 V
    • NECL Mode Operating Range:VCC = 0 V with VEE = 3.0 V to 3.6 V
    • IN/INb Inputs Accept LVPECL, LVNECL, LVDS Levels
    • A Logic High on the EN Pin Will Force Q to Logic Low
    • D10:0 Can Select Either LVPECL, LVCMOS, or LVTTL Input Levels
    • VBB Output Reference Voltage

    MC100EP195BMNGONMC100EP195B 是一款可编程延迟芯片 (PDC),主要用于时钟去歪曲和计时调整。它提供了差分 NECL/PECL 输入转换的可变延迟。 延迟部分由一个可编程的门极和多工器矩阵组成,如图 2 逻辑图所示。 EP195B 延迟增量的可数字选择分辨率约为 10 ps,净范围最高 10.2 ns。所需延迟由 10 个数据选择输入 D(9:0) 值选择,由 LEN(引脚 10)控制。LEN 上的低电平可实现 D(9:0) 确定的实时延迟值的透明加载模式。LEN 上的低电平-高电平转换将针对 D(10:0) 中的 任何后续变化锁定并保持现有电流值。表 6 和图 3 中显示了与 D0 (LSB) 至 D9 (MSB) 相关联的各种抽头数的恰当延迟值。 立即购买
