The design and implementation of a stable reference source at 258 MHz using subharmonically locked oscillation is described. The stability of the oscillator is achieved by locking a synchronous oscillator (SO) to a stable crystal oscillator, the stability of which is to be transferred to the SO, oscillating at a subharmonic frequency of the required output frequency. The reference source is a low‐voltage (1.2 V) and low‐current (1.18 mA) consumption design. This type of reference source is potentially very useful in fixed frequency mobile receivers and transmitters where crystal referred frequency stability, supply voltage, current consumption, and size are major design constraints. © 1993 John Wiley & sons, Inc.
