Divide by: 64/65/72 triple modulus low power ECL prescaler
SA702
DESCRIPTION
The SA702 triple modulus (Divide By 64/65/72) low power ECL prescaler is used in synthesizer systems to achieve low phase lock time, broad operating range, high reference frequency and small frequency step sizes. 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.
