MSM7510
300 bps Full Duplex FSK Modem – ITU-T V.21
GENERAL DESCRIPTION
The MSM7510 is useful for the ITU-T V.21 modem, for examples, low cost built-in modems,
telecontrol systems, home security systems, etc.
The family version, MSM7512B for ITU-T V.23, 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
• Conforms to ITU-T V.21, 300 bps Full Duplex
• ITU-T V.25 Answer Tone (2100 Hz) with Generator/Detector
• Single Power Supply : +3 V to +5 V
• Low Power Consumption
• Line Hybrid Circuit on Chip (direct drive capability of 600W)
• ALB (Analog–Loop back) with test mode.
• 3.579545 MHz Crystal Oscillator
• Digital Interface:
• Package options:
Operating Mode:
Power Down Mode :
16-pin plastic DIP
24-pin plastic SOP
