    PCS1900 bands over extreme temperature conditions. Inside the chip, the VCO differential output signals are fed into the output buffer, the OPLL input feedback buffer, and the calibration circuit. The off chip signal is transformed into a single ended output which needs impedance matching to 50Ωto drive the power amplifier. Like RF VCO, the oscillation bandwidth is partitioned into 128 (or 64) sub-bands for DCS/ PCS TX VCO to cover the process and temperature variation.
