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. 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.
