PCT No. PCT/FI95/00320 Sec. 371 Date Dec. 6, 1996 Sec. 102(e) Date Dec. 6, 1996 PCT Filed Jun. 5, 1995 PCT Pub. No. WO95/34133 PCT Pub. Date Dec. 14, 1995A phase locked loop (PLL) includes a phase comparator (12), a charge pump (13), a loop filter (14) and a voltage controlled oscillator (15). In order to minimize the lock-in time of the PLL under conditions of varying external temperatures, the PLL is supplied with temperature measurements, and the output of the charge pump is controlled according to both the external temperature and a desired frequency.
