Philips Semiconductors Application note Low power single/dual frequency synthesizers: UMA1017M/1018M/1019M(AM)/1020M(AM) Author: P. Hugues AN95102 UMA1018M and UMA1020M/UMA1020AM low power dual frequency synthesizers UMA1017M and UMA1019M/UMA1019AM low power single frequency synthesizers www.datasheet4u.com SUMMARY This application note describes the UMA1018M and UMA1020M/UMA1020AM from Philips Semiconductors. They permit a low-voltage low-power single-chip solution to designing dual PLL frequency synthesizers. They are intended for use in digital or analogue wireless communications equipment. Typical applications include GSM, DECT and DCS1800. Three low-voltage low-power solutions to single frequency synthesizers are also briefly described.
