Product Summary
The msm7512brsis a 1200 bps Half Duplex FSK Modem. The msm7512brsis useful for the ITU-T V.23 modem, for examples, low cost built-in modems, telecontrol systems, home security systems, etc. Oki has been mass-producing and delivering the msm7512brsfor 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.
