SP8853A/B
1·3GHz Professional Synthesiser
The SP8853 is a low power single chip synthesiser
intended for professional radio applications, containing all the
elements (apart from the loop amplifier) required to build a PLL
frequency synthesis loop
The device is serially programmable by a three-wire data
highway and contains three independent buffers to store one
reference divider word and two local oscillator divider words.
A digital phase detector with two charge pumps,
programmable in phase and gain, are provided to improve
lock-up performance. The preset operation of the charge
pumps can be overwritten or the comparison frequencies
switched to output ports under control of the divider word. The
dual modulus ratio and so operating range is also
programmable through the same word.
A power down mode is incorporated as a battery economy
feature.
The SP8853 is specified at 1·3GHz at
