MSM7512B
1200 bps Half Duplex FSK Modem – ITU-T V.23
This version: MJaSnM. 71599182B
Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM7512B is useful for the ITU-T V.23 modem, for examples, low cost built-in modems,
telecontrol systems, home security systems, etc.
The family version, MSM7510 for ITU-T V.21, will be available following this device.
Oki has been mass-producing and delivering the MSM6926 and 6927 for a long time, but these
devices need two power supplies, +5 V for digital and +12 V for analog.
New generation devices, MSM7510/7512B, work with single rail +3 V to +5 V and low power
consumption.
