Description

The Electronic Component Model 8853A2-S3C belongs to the product category of IC Chips. It is a low power single chip synthesizer mainly used for professional radio applications. This model includes all required elements except for the loop amplifier, which is used to build a PLL frequency synthesis loop. The device can be programmed serially by a three-wire data highway and consists of three independent buffers for storing a reference divider word and two local oscillator divider words. Additionally, there is a digital phase detector with two charge pumps, programmable in phase and gain, to improve lock-up performance. The preset operation of the charge pumps can be overwritten or the comparison frequencies can be switched to output ports controlled by the divider word. The dual modulus ratio and operating range are also programmable through the same word.
