The ADF4156BCPZ-RL is a member of the product family of Voltage Controlled Oscillator (VCO) based frequency synthesizers from Analog Devices. It is a high-performance, low power, voltage controlled oscillator that operates on a single or dual supply operating range of 3.14V to 5.25V. Its operating temperature range is -40C to +85C.The ADF4156BCPZ-RL provides superior frequency accuracy and ultra-low static power consumption. With Dualband operation, the device can be used in applications requiring both high frequency and low frequency output. Its integrated PLL and VCO provide high output power of +10dBm. In addition, it features fast settling time due to its low control voltage dependency, fast switchover and low jitter performance, making it suitable for a range of high frequency applications including cellular infrastructure, radio communication systems, military, medical and automotive electronics.The frequency synthesizer of the ADF4156BCPZ-RL consists of a switching logic block, charge pump circuit, voltage controlled oscillator, frequency prescaler, reference divider and serial data interface. The frequency of the dual VCO is proportional to the control voltage. A serial data interface is provided for programming the registers of the device. The timing of each stage is set either by the input frequency reference or by internal clock. The charge pump circuit is used to set the VCO frequency.The switching logic block contains two phase-selectable digital phase locked loops that are used to lock onto the desired frequency. The PLL operates on the input reference signal and generates a digital code that is used by the frequency prescaler. The output of the prescaler can be tuned by the external control voltage. The frequency of the output signal is modified by the reference divider, whereas the frequency prescaler and charge pump circuit adjusts the frequency of the VCO.The ADF4156BCPZ-RL is ideal for a wide variety of applications such as radio receivers, cell phone base stations, digital TVs, satellite receivers and transmitters, cordless phones and digital cameras. It is also used in test and measurement systems and telecom equipment. The device is available in a RoHS-compliant, 4mm x 4mm, 32-lead TQFN package.In conclusion, the ADF4156BCPZ-RL is a high performance, low power, voltage controlled oscillator based frequency synthesizer. It features superior frequency accuracy, dual band operation, fast switching times and low jitter performance, making it suitable for a variety of high frequency applications. It is available in a RoHS-compliant 4mm x 4mm, 32-lead TQFN package, making it an ideal choice for applications where size and power efficiency are essential. It is an ideal solution for a range of applications such as radio receivers, cell phone base stations, digital TVs, satellite receivers and transmitters, cordless phones and digital cameras as well as test and measurement systems and telecom equipment.
