SP5658

2.7GHz 3-Wire Bus Controlled Frequency Synthesiser

Advance Information

Supersedes October 1996 Media IC Handbook HB3923-2

DS4064 - 4.1 March 1998

The SP5658 is a single chip frequency synthesiser

designed for tuning systems up to 2.7GHz.

The RF preamplifer contains a divide by two prescaler

which can be disabled for applications up to 2GHz so enabling

a step size equal to the comparison frequency up to 2GHz and

twice the comparison frequency up to 2.7GHz.

Comparison frequencies are obtained either from a crystal

controlled on–chip oscillator or from an external source.

The device contains two switching ports, in the 14 pin

version and four in the 16 pin, together with an ‘‘in–lock” flag

output. The device also contains a varactor line disable and

charge pump disable facility.
