SA8025A
1.8GHz low-voltage Fractional-N synthesizer

DESCRIPTION
The SA8025A is a monolithic low power, high performance dual
frequency synthesizer fabricated in QUBiC BiCMOS technology.
The SA8025A is an improved version of the SA8025, suitable for
narrow band systems like the Japan Personal Digital Cellular (PDC)
system. The new design improves the performance of the fractional
spur compensation circuitry. The new version is pin-for-pin
compatible with the previous version. Featuring Fractional-N
division with selectable modulo 5 or 8 implemented in the Main
synthesizer to allow the phase detector comparison frequency to be
five or eight times the channel spacing. This feature reduces the
overall division ratio yielding a lower noise floor and faster channel
switching. The phase detectors and charge pumps are designed to
achieve phase detector comparison frequencies up to 5MHz. A four
modulus prescaler (divide by 64/65/68/73) is integrated on chip with
a maximum input frequency of 1.8GHz at 3V. Programming and
channel selection are realized by a high speed 3-wire serial
interface. A 1GHz version (SA7025DK) is also available with the
same pinout.
