MC33594FTA

PLL Tuned UHF Receiver for Data Transfer Applications

NXP Semiconductors. 

Freescale SMeCm33ic59o4nductor, Inc.

ELECTRICAL CHARACTERISTICS

Unless otherwise specified, VCC=[4.5V;5.5V], operating temperature range TA=[-40°C;+105°C]. Values refer

to the circuit in recommended in the application schematic (see figure 17), unless otherwise specified. Typical

values reflect average measurement at VCC=5V, TA=25°C, using MC33594 (500kHz IF bandwidth).
