SP8858  
1·5GHz Professional Synthesiser  
Supersedes March 1997 version, DS3843 - 3.0  
DS3843 - 4.1 July 1998  
The SP8858 is a single chip synthesiser intended for PLL  
signal synthesis applications up to 1.5GHz and includes a  
dual modulus prescaler (4N/N11), programmable A, M and  
R dividers, digital phase detector, charge pump and lock  
detect circuits.  
The SP8858 is a development of the SP8853 synthesiser  
with low residual phase noise, increased dynamic range  
above 1GHz and an improved high gain phase detector  
design that eliminates the dead-band.  
The low prescaler modulus, programmable to either 16/17  
or 8/9, together with the 15-bit M counter and 13-bit reference  
counter make this device ideal for a diverse range of high  
performance applications.  
The nominal phase detector gain is set by a reference  
current into pin 24 and the gain can be varied over a 4:1 range  
when the device is programmed. The dividers, the phase  
detector sense, the prescaler modulus and the data buffer  
control logic are also programmable using the three wire  
serial interface. An alternative 22-bit control word for the A  
and M dividers and phase detector gain can be stored so  
allowing fast frequency hopping and bandwidth switching by  
simply toggling the logic level on pin 13 (F1/F2). In addition,  
the A counter of the ‘active’ buffer can be programmed with  
only 6 bits, allowing fast hopping to adjacent channels.  
A simple exclusive - or lock detect circuit is also provided,
