FM IF IC
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 high-
speed data communication, DECT, wireless LAN, keyless
entry systems, etc.
The TK14584M is available in the very small SSOP-12
surface mount package.
