TK14551V - TOKO

TK14551V FM IF DETECTOR/AMPLIFIER

The TK14551V is a wide band IF IC capable of operating up to 90 MHz. It includes an FM demodulator, RSSI, RSSI comparator and data comparator. These functions can perform high-speed operations. The TK14551V has a unique function that allows establishing the demodulation characteristics by changing the external RC time constant, and not changing the phase shi.
