MSM7510/7512B Application Notes
ITU-T V.21/ITU-T V.23 Based Single Power Supply FSK Modem

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.
This instruction manual introduces standard application examples to customers who
design modems. This manual does not include the specifications for MSM7510 and
MSM7512B. Refer to separate data sheets for that information.
