General Description

The HT9015 is an RF single chip for cordless

phone systems. Internally these are three major

parts, a PLL, an IF decoder and a compander.

nal strength and built-in noise detector for S/N

quality.

The compander provides better S/N ratio for

audio signal processing.

The PLL provides radio channel selection for

either the transmitter or receiver. Frequency

locking status of the selected channel can be

monitored by a control register.

The HT9015 has a wide-range applications in

FM/FSK, Transmitting/Receiving of VHF

bandwidth including cordless phone, narrow

band voice and data transceiver systems.

The IF decoder provides two frequency down

converters that let high frequency signals pass

through a mixer and local oscillator to be low-

ered for frequency even base band signals. It

also provides an RSSI (receiver signal strength

indicator) function to detect the IF output sig-

The most significant advantage of the HT9015

is in the reduction of many external compo-

nents making it well suited for cordless phone

baseset, handset radio section.
