• Local Oscillator Source  FM/FSK Transmitter  Wireless Data Transmitters  433/868/915MHz ISM Band Systems  Low-Cost Single Frequency LO Source  Wireless Security Systems The RF2510 is a monolithic integrated circuit intended for use as a low-cost Frequency Synthesizer. The device is provided in a 16 pin SSOP package and is designed to provide a phased locked frequency source for use in local oscillator or transmitter applications. The chip can be used in FM or FSK applications in the U.S. 915MHz ISM band and European 433MHz and 868MHz ISM band. The integrated VCO, dual modulus/dual divide (128/129 or 64/65) pre-scaler, and reference oscillator require only the addition of an external crystal to provide a complete phase-locked oscillator.

Pin Function Description Interface Schematic 1O S C B This pin is connected directly to the reference oscillator transistor base. The intended reference oscillator configuration is a modified Colpitts. An appropriate capacitor as chosen by the customer should be con- nected between pin 1 and pin 2. 2O S C E This pin is connected directly to the emitter of the reference oscillator transistor. An appropriate capacitor as chosen by the customer should be connected from this pin to ground. See pin 1. 3G N D 1 Ground connection for the VCO OUT buffer amp. 4V C O O U T B u f f e r e do u t p u to ft h eV C O 5V C C This pin is used to supply DC bias to the entire IC. ARF Bypass capac- itor should be connected directly to ground. 6G N D Ground connection. 7P D Power Down control for all circuitry. When this pin is a logic “low” all cir- cuits are turned off. 8N C Not internally connected. 9 MOD CTRL This pin is used to select the prescaler modulus. A logic “high” selects 64 or 128 for the prescaler divisor. A logic “low” selects 65 or 129 for the prescaler divisor. 10 DIV CTRL This pin is used to select the desired prescaler divisor. A logic “high” selects the 64/65 divisor. A logic low selects the 128/129 divisor.

11 RESNTR- The RESNTR pins are used to supply DC voltage to the VCO, as well

as to tune the center frequency of the VCO. Equal value inductors should be connected to this pin and pin 13.

12 MOD IN FM analog or digital modulation can be imparted to the VCO through

this pin. The VCO varies in accordance to the voltage level presented to this pin. To set the deviation to a desired level, a voltage divider refer- enced to Vcc is recommended. Because the modulation varactors are part of the resonator tank, the deviation is slightly dependent upon the components used in the external tank. See pin 11. 13 RESNTR+ See pin 11. See pin 11. 14 LOOP FLT Output of the charge pump. An RC network from this pin to ground is used to establish the PLL bandwidth.

15 VREF P Bias voltage reference pin for bypassing the prescaler and phase
