SN65CML100DGK General Description

This high-speed translator/repeater is designed for signaling rates up to 1.5 Gbps to support various high-speed network routing applications. The driver output is compatible with current-mode logic (CML) levels, and directly drives 50- loads connected to 1.8-V, 2.5-V, or 3.3-V nominal supplies. The capability for direct connection to the loads may eliminate the need for coupling capacitors. The receiver input is compatible with LVDS (TIA/EIA644), LVPECL, and CML signaling levels. The receiver tolerates a wide common-mode voltage range, and may also be directly coupled to the signal source. The internal data path from input to output is fully differential for low noise generation and low pulse-width distortion.

The V_BB pin is an internally generated voltage supply to allow operation with a single-ended LVPECL input. For single-ended LVPECL input operation, the unused differential input is connected to V_BB as a switching reference voltage. When used, decouple V_BB with a 0.01-uF capacitor and limit the current sourcing or sinking to 400 uA. When not used, V_BB should be left open.

This device is characterized for operation from 40°C to 85°C.

Shipping is very long! But it's good that the pair came in general, bought for illumination embilight a couple of pieces, everything works true through the adapter from micro to mini did not connect only the diode burned bought a cord of norms at once all earned and passed!

C**l 11/29/2020

One stock-everything is fine!

H**r 02/25/2020

The sensor is a flask with a metal ball inside. You know what precision is. Came for three weeks, threw in the mailbox.

S**l 01/31/2020

Not tested yet but fast delivery and compliant product, impeccable
