Description

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 shifter constant. The RSSI output is individually trimmed, resulting in excellent accuracy, good linearity, and stable temperature characteristics. Because the TK14551V includes a dual high-speed RSSI output, it is possible to demodulate AM simply and to sense the carrier level at the same time.

Therefore, the TK14551V is suitable for high-speed data communication and can be used for various applications.

The TK14551V is available in the very small TSSOP-24 surface mount package.
