Overview
The LV2700V provides the reception and transmission
functions necessary for half-duplex communication in
spread-spectrum communications systems.
Features
Can be used in weak radio wave band without frequency
conversion (direct signal processing at 236 MHz)
Can also be used in the ISM band (900MHz, 2.4GHz)
with frequency conversion
Wide spread-spectrum bandwidth (20 MHz)
Sanyo developed system for PN code synchronization
Allows direct primary modulation (FSK and FM) by
data and analog signals.
Data transfer at a maximum rate of 256kbps can be
made (when the built-in LPF is used)
Low-voltage operation (2.7 to 5.5 V)
Low power dissipation (36 mW in RX mode)
Small package: SSOP30
