Features
Integrated PLL Loop Filter
ESD Protection also at ANT1/ANT2
(4 kV HBM/200V MM; Except Pin 2: 4 kV HBM/100V MM)
High Output Power (5.5 dBm) with Low Supply Current (8.5 mA)
Modulation Scheme ASK/FSK
– FSK Modulation is Achieved by Connecting an Additional Capacitor Between the
XTAL Load Capacitor and the Open Drain Output of the Modulating Microcontroller
Easy to Design-in Due to Excellent Isolation of the PLL from the PA and Power Supply
Single Li-cell for Power Supply
Supply Voltage 2.0V to 4.0V in the Temperature Range of –40°C to +85°C/+125°C
Package TSSOP8L
Single-ended Antenna Output with High Efficient Power Amplifier
CLK Output for Clocking the Microcontroller
One-chip Solution with Minimum External Circuitry
125°C Operation for Tire Pressure Systems
UHF ASK/FSK
Transmitter
T5750
1. Description
The T5750 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 868 MHz to 928 MHz. It can be used in both FSK and ASK
systems.
