New Open Eye MSA Accelerates Adoption of PAM-4 Optical Interconnects

SR4 for 100 meters reach over a multi-mode fiber and LR for 10 kilometers reach over a single-mode fiber. Defines the requirements for analog PAM-4 solutions for 50G SFP, 100G DSFP, 100G SFP-DD, 200G QSFP, 400G QSFP-DD and OSFP modules. Ideal for 53 Gbps SFP28 LR and 200 Gbps QSFP SR optical module designs for next generation 5G wireless, enterprise and data center networking applications.

Compact Buck-Boost Regulator delivers up to 300 mA.
Controls & Controllers

Compact Buck-Boost Regulator delivers up to 300 mA.

Respectively rated to 300 and 275 mA, 3.3 V SC630A and 5 V SC632A come in 2 x 2 x 0.6 mm MLPQ 8-pin package and are designed to be used with 2.2 -µF capacitors. Both 3-mode (1x, 1.5x, 2x) charge pumps have 1 MHz fixed frequency, deliver continuous output currents, and operate as LDO linear regulators when input exceeds output. When input is less than required output, devices automatically...

Construction Equipment and Supplies

Current Sink LED Backlight Drivers minimize component count.

Intended for high-end handheld displays, SC667 and SC668 can replace boost converters and charge pumps in high-end handhelds while providing display backlighting. Both incorporate smart Automatic Dropout Prevention (ADP) technology, which enables automatic and simultaneous monitoring of each current sink to avoid dropout as system loads turn on and off. While SC668 provides 8 current sinks, SC667...
