µ

PC8002

SECOND MIXER + IF AMPLIFIER

FOR DIGITAL CORDLESS TELEPHONES

The µPC8002 is a monolithic IC developed for use in digital cordless telephones. Its internal equivalent circuits

comprise a double balanced mixer (DBM), IF amplifier circuit, and RSSI (Received Signal Strength Indicator) circuit.

µ

PC8002 can operate on a wide range of power supply voltages from 2.7 V to 5.5 V, and incorporates a power-

The off function, making it ideal for achieving low set power consumption.

The package is a 20-pin plastic shrink SOP (225 mil) suitable for high-density surface mounting.

FEATURES

• Low-voltage, low-consumption-current operation possible (VCC = 2.7 to 5.5 V, ICC = 3.4 mA at VCC = 3 V)

• Wide mixer input frequency range (fMIX = 250 MHz (TYP.) to 500 MHz (MAX.))

• Wide IF amplifier input frequency range (fIF = 8 MHz (MIN.) to 12 MHz (MAX.), 10.7 MHz (TYP.))

• High limiting sensitivity (S

• Wide RSSI dynamic range (DR = 85 dB (TYP.))

• On-chip power-off function

• Use of 20-pin plastic shrink SOP (225 mil) allows high-density surface mounting

L = –100 dBm (TYP.))

Caution Product quality may suffer if the absolute rating is exceeded for any parameter, even momentarily.

In other words, an absolute maximum rating is a value at which the possibility of physical damage to the product cannot be ruled out. Care must therefore be taken to ensure that the these ratings are not exceeded during use of the product.
