The SA701 is an advanced dual modulus (Divide By 128/129 or 64/65) low power ECL prescaler. The minimum supply voltage is 2.7V and is compatible with the CMOS UMA1005 synthesizer from Philips and other logic circuits. The low supply current allows application in battery operated low-power equipment. Maximum input signal frequency is 1.1GHz for cellular and other land mobile applications. There is no lower frequency limit due to a fully static design. The circuit is implemented in ECL technology on the QUBiC process. The circuit will be available in an 8-pin SO package with 150 mil package width and in 8-pin dual in-line plastic package, and is pin compatible with Fujitsu MB501, Plessey SP8704 and Motorola MC12022.
