FEATURES
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.
