HXT6104-DNT/C – 4-Channel 16 Gb/s VCSEL Laser Driver IC – Renesas

The Renesas HXT6104-DNT/C is a 4-channel, 16 Gb/s VCSEL laser driver IC supplied in bare-die (wafer) form for compact, low-power optical transmitter modules. Available now for RFQ from Pacific Component Xchange.

The Renesas HXT6104-DNT/C is a 4-channel VCSEL (Vertical-Cavity Surface-Emitting Laser) driver IC operating at up to 16 Gb/s per channel. Designed for compact, robust, low-power optical transmitter modules, the HXT6104 handles the complete digital-to-optical conversion chain, including the CML input stage, laser driver, drive control, and supervision functions. In combination with a VCSEL array, it forms a key building block for high-speed datacom optical links. The -DNT designation indicates the device is supplied in die (wafer) form for direct module integration, and this listing covers the HXT6104-DNT/C variant. (Note: the HXT6104 was originally an Integrated Device Technology (IDT) part and is now offered under the Renesas Electronics brand.)

Note: Despite occasionally appearing in memory-component lists, the HXT6104-DNT/C is an optical-interconnect laser driver IC, not a memory device.
