Features

• Adjustmet-free VCO : Eliminates the need to adjust free-

running frequency.

• Good temperature characteristics of VCO : ±0.1% typ.

for ±50°C change.

• No antibirdie filter is required because a measure is taken

against adjacent channel interference.

• Less carrier leak 19kHz : 53dB 38kHz : 50dB

• The on-chip cal-tone signal generator facilitates applica-

tion of recording calibrator.

• Low distortion
