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.
