DESCRIPTION
The SA7025 is a monolithic low power, high performance dual
frequency synthesizer fabricated in QUBiC BiCMOS technology.
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 triple modulus prescaler (divide by
64/65/72) is integrated on chip with a maximum input frequency of
1.04GHz. Programming and channel selection are realized by a
high speed 3-wire serial interface.
