MACOM Technology Solutions unveiled the MALD-37345, a quad 28G VCSEL driver with input equaliser, and the MATA-37344, a quad 28G transimpedance amplifier (TIS). This complete transmit/receive solution is targeted for short reach, VCSEL-based 100 Gbps onboard optics, but is also suited for optical modules and active optical cable applications.
This chipset addition to MACOM’s portfolio of short reach VCSEL drivers and TIAs is a next generation evolution of currently shipping MALD-37045 and MATA-37044, with the new chipset eliminating the need for clock data recovery (CDR). It is also backwards pin compatible with those devices, giving customers the flexibility to mix and match parts to include or not include a CDR.
The VCSEL driver of the MALD-37345 includes programmable eye-shaping features and an input equaliser. The high-sensitivity TIA of the MATA-37344 features selectable bandwidth to support up to 28,05 Gbps and lower speed legacy data rates, as well as an output driver with programmable output swing and 2-tap de-emphasis. Both devices are available in 2 x 3 mm die form, supplied in waffle packs, whole wafers or quartered wafers.
