Single-chip Wireless ASK/OOK (ON-OFF Keying) RF Receiving Module
DL-RXS531R is the new generation single-chip wireless ASK/OOK (ON-OFF Keying) receiving module,which is mainly used in the field of wireless radio frequency remote control. Compared with previous generation products, DL-RXS531 has higher sensitivity, which can reach -109dBm in 433MHz application environment, greatly increasing the receiving distance. Meanwhile, this model has a higher integration,with high frequency signal reception functions all on chip, to achieve the most reliable receiving results, with the least peripherals and the lowest cost.
DL-RXS531 is a real "high frequency antenna AM signal input, digital signal output" receiving module with French imported single chip design. All RF and IF tuning is done automatically on the chip, which eliminates the manual adjustment process in the development and production, will reduce your R&D costs and enhance the product competitiveness.
This RF module is compact in shape and less than 1cm in width, is the best choice for small space applications. This module has a preset CE enabled control pin, which can be well used in power saving mode, to achieve a better average power consumption. It also has super anti-interference ability.
Features
● Standard COMS interface control and decoding data output
● Complete monolithic UHF receiver, frequency range 300-450 MHz
● Receive sensitivity: -109dBm (315MHz), -109dBm (433MHz)
● Transmission rate: 2.5 kbps (SWP), 10 kbps (FIXED) auto tuning
● No need for manual adjustment, no need for external filters and inductors
● Preset CE enabled control pin to shift sleep / wake-up (Low level effective).
● Common frequencies: 433M, 315M, 390M, adopt different local oscillation crystals;
● 4.5mA (315MHz, full operation); 0.5uA (shutdown mode); 370uA at “CE = High” (315MHz, 10:1 duty ratio)
● WOR function is used to enable external decoder board and MCU, RF antenna radiation is very low
