<p>The HCSL output structure is open-drain and can be direct coupled or AC coupled to HCSL receivers with appropriate termination scheme. This output structure supports either on-chip 50-&Omega; termination or off-chip 50-&Omega; termination. The on-chip, 50-&Omega; termination is provided primarily for convenience when driving short traces. In the case of driving long traces possibly through a connector, the on-chip termination must be disabled and a 50 &Omega; to GND termination at the receiver must be implemented. The output supplies can be operated from 1.8 V, 2.5 V, or 3.3 V without any impact on jitter performance or other AC or DC specifications. The LVCMOS outputs on each side (P and N) can be configured individually to be complementary or in-phase or can be turned off (high output impedance). The LVCMOS outputs are always at 1.8-V logic level irrespective of the output supply. In case 3.3-V LVCMOS outputs are required, STATUS1 and/or STATUS0 can be configured as 3.3-V LVCMOS outputs.</p> <p><span data-slate-node="text"> </span><span data-slate-node="text"

LMX2572</p><div>您好，我采购了贵司的LMX2572芯片，我们需要一年稳定采购 TI 芯片 1 万片以上 ，现在量产项目遇到 LMX2572芯片寄存器配置上的问题<strong>，</strong>想使用芯片上自带的自动斜坡扫描模式和2FSK调制模式，但每次以进行配置就会影响我输出的3.4GHz的主频率，主频率不输出了，而且模式也没成功开启，寄存器会重新被修改，导致对主频率输出影响。需要技术紧急支持 。同时我们后续还有多个新项目，希望对接大客户专属团队，建立长期合作。麻烦帮我转接或安排资深工程师尽快回电，谢谢！</div> <div>&nbsp;</div>https://e2echina.ti.com/thread/3850964?ContentTypeID=1Wed, 22 Apr 2026 03:14:36

Tee(Mini的MBT-283+)上产生带偏置的时钟信号给到下一级使用，想问一下他们之间直接交流耦合连接就可以，不知道是否需要在MBT-283+输入端端接100电阻(或下拉50欧电阻)？下图是MBT-283+的规格数截图。<img

<p data-end="1712" data-start="1473">In the datasheet, the 100 &Omega; differential resistor is placed before the AC coupling capacitors.
