DESCRIPTIONS

The PLL502-67 is high performance and low phase

noise VCXO IC chip. It provides phase noise per-

formance as low as –140dBc at 1kHz offset (at

17.664MHz) and –125dBc at 1kHz offset at

155.52MHz by multiplying the input crystal frequency

up to 8x. The wide pull range (+/- 190 ppm) and very

low jitter makes this chip ideal for a wide range of

applications, from xDSL to SONET/SDH and FEC.

The chip accepts a low cost fundamental parallel

resonant mode crystal from 12 to 25MHz.
