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.

鈥?Band limiting filter (LPF) for data transmission

[RX Block]

鈥?Spectrum despreader

鈥?Synchronization supplementation and protection

鈥?236-MHz PLL

鈥?PN code generator (M sequence)

鈥?M sequence code length (31 or 63 chips) and tap

switching

鈥?FSK (FM) demodulator

鈥?Lock detector

Features

鈥?Frequency conversion is not required.

(direct signal processing at 236 MHz)

鈥?Wide spread-spectrum bandwidth (20 MHz)

鈥?Sanyo developed system for PN code synchronization

鈥?Allows direct primary modulation (FSK and FM) by

data and analog signals. (Maximum data rate: 150 kbps)

鈥?Low-voltage operation (2.7 to 5.5 V)

鈥?Low power dissipation (36 mW in RX mode)
