FM IF IC
DESCRIPTION
The TK14588V is a standard function general purpose IF
IC capable of operating up to 22 MHz. The TK14588V
contains a high-speed data comparator for base band
processing. The TK14588V 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 TK14588V
was developed for high-speed data communication, DECT,
wireless LAN, keyless entry systems, etc.
The TK14588V is available in the very small TSSOP-16
surface mount package.
