ELECTRICAL CHARACTERISTICS (continued)

Test conditions (unless otherwise stated)

Tamb= See note 7. Vee= 0V, Vcc = 4.75 to 5.25 V, Fif = 479.5 MHz, IF bandwidth ± 30 MHz, output ampltude -11dBV

These characteristics are guaranteed by either production test or design. They apply within the specified ambient temperature

and supply voltage unless otherwise stated.

Performance not guaranteed over full specified IF input operating range.

I Q crosstalk is determined from the gain and phase match by the following formula.

Crosstalk = 20* Log (tan(phase error + Atan (1+amplitude imbalance) -45°)).

Over specified gain dynamic range, 1KΩ and 15pF load up to 30MHz baseband.

Over specified gain dynamic range, 1KΩ and 15pF load up to 15MHz baseband.

Over specified gain dynamic range, 1KΩ and 15pF load up to 30MHz baseband.

The device should not be operated beyond the point of output clipping since gain match may be

compromised.

* Operating temperature range for the SL1714 is 0°C to 70°C. This applies to applications featuring a double sided

copper board. For other applications not using such a board, the maximum operating temperature may be

reduced. Operating temperature range for the SL1714C is 0° to 85°C.

Operation above the recommended IQ output level may result in outputs with harmonic performance degraded.
