TH72001 is a single-chip transmitter chip, designed with a standard line with EN 300220 and some similar standards. It can be used in keyless entry systems, remote telemetry systems, data communications systems and security and other systems. The main technical characteristics are as follows: • Operating frequency is 290 ~ 350 MHz; • Single-ended RF output; • FSK modulation; • FSK modulates through crystal pulling and FSK modulates at rate of DC ~ 40 Kb / s;• Power supply is l .9 ~ 5.5 V; • Operating current is 3.5 ~ 10.7mA and standby current is 0.1μA; • Output power is adjustable within -15 ~ +6 dBm.
