MC33596
PLL Tuned UHF Receiver for Data Transfer Applications
1
Overview
GNDSUBD
The MC33596 is a highly integrated receiver
designed for low-voltage applications. It includes a
programmable PLL for multi-channel applications,
an RSSI circuit, a strobe oscillator that periodically
wakes up the receiver while a data manager checks
the content of incoming messages. A configuration
switching feature allows automatic changing of the
configuration between two programmable settings
without the need of an MCU.
