LV2700V Overview
EN 5651 Bi-CMOS LSI LV2700V Spread Spectrum munications IC Preliminary 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...
LV2700V Key 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)
- Spectrum spreader
- Crystal oscillator circuit
- PN code generator (M sequence)
- M sequence code length (31 or 63 chips) and tap switching
