LV2700V
LV2700V is Spread Spectrum Communications IC manufactured by SANYO.
Overview
The LV2700V provides the reception and transmission functions necessary for half-duplex munication in spread-spectrum munications systems.
- 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
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 m W in RX mode)
