Single power supplies MSM7510 and MSM7512B are LSIs for modems based on ITU-T
V.21 and V.23 respectively.
MSM7510/7512B are upgrades of MSM6926/MSM6927, earlier versions that have been
in use for some time. Power supplies that once required two lines (5 V, 12 V) now require
only one, and have a wide operation range (2.7 V to 5.5 V). The analog system interface
has also been simplified. The resistance hybrid circuit, which was external, is now
onboard an LSI so that the 600 W transformer can be directly driven.
Single power supply FSK modems can be applied to a wide range of fields, such as telecontrol
systems and home security systems.
