GE VMIVME-3122-210-VMIVME3122 CPU board
VMIVME-3122 is a member of VMIC’s wide range of VMEbus analog input/output products. VMIVME-3122 has 16-bit digital resolution, program-controlled gain, optional conversion rate and 64-channel differential or single-ended analog input automatic scanning function, which can provide excellent dynamic range and analog input channel density. Support various working modes, including automatic scanning, data burst and external synchronization
Step. The board is designed to directly interface with the signal conditioning board series of VMIC to digitize the output of thermocouple, RTD and strain gauge. The gain of a single channel can be downloaded for scanning operation, or the circuit board can be configured as a fixed gain common to all channels. Multiple circuit boards can be synchronized together, enabling up to 16 circuit boards to start each scan at the same time. Interval timers, bus interrupters, channel counters and the Midscan/Endscan flag simplify data monitoring in the dual-port data buffer. The system applications benefiting from the VMIVME-3122 function include plant I automation, process control, data acquisition system, training simulator and laboratory instruments. The following brief overview of the main functions describes the flexibility and performance available VMIVME-3122:16, 32 or 64-channel differential or single-ended analog input 16-bit analog-to-digital conversion 381 Hz to 100 kHz optional scan rate for high performance options, 381 Hz to 50 kHz for programmable gain of standard performance options x1 or x10.
For CFP2 and QSFP28, Mitsubishi Electric has TOSA and ROSA that integrate chips of four wavelengths into one package, corresponding to 100G and 200G; For CFP8, 400G transmission can be achieved by using two TOSAs.
Mitsubishi Electric’s 100GBOX packaged TOSA drives four EML chips of LAN-WDM4 wavelength respectively, and VMIVME-3122 combines output through optical combiner; Corresponding to the speed of Ethernet and OTU4, using PAM4 drive can also reach 200G, and the transmission distance can cover 40km.
Mitsubishi’s 100GBOX package ROSA has four APDs operating at 25G, and VMIVME-3122 can achieve the reception sensitivity with less power consumption. The transmission distance can reach 40km with the simultaneous use of error correction technology.
In addition, BOX-TOSA of 400Gb/s can be transmitted at 8 wavelengths. Two BOX can be combined to cover the 8 wavelengths of LAN-WDM. VMIVME-3122 corresponds to the 4-level modulation of PAM4 through their respective wavelengths. Each wavelength can transmit 50Gb/s, and the whole can transmit 400Gb/s. The transmission distance of 400G can reach up to 10km.
In short, Mitsubishi Electric can provide customers with various speed devices and provide a variety of devices in an easy-to-use form to ensure quality and reliability in development and mass production. In terms of transmission rate, it covers all transmission rates such as 10G, 25G, 100G and 400G. In terms of convenience of use, while maintaining the industry standard 4-pin TO-CAN product, the same device can also correspond to PAM4 modulation, low power consumption, easy to install into optical transceiver, etc. In terms of product series, it supports various wavelengths, VMIVME-3122 has direct modulation laser and external modulation EML laser, BOX and CAN packaging types and other options.
