DESCRIPTION
The TK14584M is a standard function general purpose IF IC capable of operating up to 22 MHz. The TK14584M 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. The TK14584M was developed for highspeed data communication, DECT, wireless LAN, keyless entry systems, etc. The TK14584M is available in the very small SSOP-12 surface mount package.
