FEATURES

Selectable multipliers (x2.5, x2.75, x3, x4.25, x5, x12.5). Crystal input range, 13MHz to 31MHz (see Se- lection Table for detailed acceptable input ranges). Maximum output frequency: 312.5MHz 2 CMOS outputs. Selectable output drive (Standard or High-Drive). Selectable REF_CLK output. 3.3V operation. Available in 14-Pin SOIC.

DESCRIPTION

The PLL601-12 is a highly flexible XO with select- able multipliers and two CMOS outputs (one of which can be selected to be REF_CLK). Thanks to Phase- Link’s advanced Phase Locked Loop technology, it allows a wide choice of selectable multipliers that permits the user to achieve useful frequencies from standard low cost crystals. It accepts fundamental parallel resonant mode crystals from 13 to 31MHz, and is ideal to generate 156.25MHz from a standard 25MHz crystal.

XIN I Crystal input. XOUT I Crystal output. I I Multiplier selector pins. These pins have an internal pull-up that will de- fault SEL to ‘1’ when not connected to GND. DRIVE_SEL I Selector pin. If DRIVE_SEL is ‘0’, outputs are at high drive. If ‘1’ or not connected, outputs are standard drive (internal pull-up). GND 7,8 P Ground. CLK1 O CLK1 output is the output of the reference frequency (crystal) after multi- plication through the Phase Locked Loop. CLK2/REF_CLK O CLK2 or REF_CLK output (depending on REF_SEL). CLK2 is in phase and at the same frequency as CLK1. REF_CLK provides the same output as the crystal reference. REF_SEL I Selector pin. This pin if set to ‘0’ selects REF_CLK on pin 10. If not con- nected, it defaults to ‘1’ (pin 10 = CLK2). Internal pull-up. I I Multiplier selector pins. These pins have an internal pull-up that will de- fault SEL to ‘1’ when not connected to GND.
