MSM7512中文资料1200 bps Half Duplex FSK Modem – ITU-T V.23数据手册OKI规格书

描述 Description

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.FEATURES
