Atmel T5754
The T5754 is a PLL transmitter IC which has been developed for the demands of RF low-cost transmission systems at data rates up to 32 kBaud. The transmitting frequency range is 429 MHz to 439 MHz. It can be used in both FSK and ASK systems.FEATURES
● Integrated PLL Loop Filter● ESD Protection (4 kV HBM/200 V MM; Except Pin 2: 4 kV HBM/100 V MM) also at ANT1/ANT2
● High Output Power (7.5 dBm) with Low Supply Current (9.0 mA)
● Modulation Scheme ASK/ FSK
