Jul 22, 2008 Comprised of 4 x 10.3 Gbps Transimpedance Limiting Amplifier (HXR4104) and 4 x 10.3 Gbps Vertical Cavity Surface Emitting Laser driver (HXT4104), HXR/T4104 chipset is fully programmable via 2-wire interface. This enables control of signal peaking, modulation, and average currents while also providing access to temperature and output power monitoring on channel-by-channel basis. Parallel VCSEL driver is compatible with QSFP Multi-Source Agreement (MSA).
