LV2700V
Spread Spectrum Communications IC
Preliminary
Overview
The LV2700V provides the reception and transmission
functions necessary for half-duplex communication in
spread-spectrum communications systems.
Features
• Frequency conversion is not required.
(direct signal processing at 236 MHz)
• 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. (Maximum data rate: 150 kbps)
• Low-voltage operation (2.7 to 5.5 V)
• Low power dissipation (36 mW in RX mode)
• Band limiting filter (LPF) for data transmission
[RX Block]
• Spectrum despreader
• Synchronization supplementation and protection
• 236-MHz PLL
• PN code generator (M sequence)
• M sequence code length (31 or 63 chips) and tap
switching
• FSK (FM) demodulator
• Lock detector
