Pericom Semiconductor PI6C918
The PI6C918 and PI6C919 are high-precision, low-voltage general-purpose clock generators that reach a maximum output frequency of 120 MHz. These devices use an external low-cost crystal to generate very accurate and stable system clocks. These frequency synthesizers include a crystal oscillator, a programmable PLL and an output buffer.| Part No. | PI6C918 |

● No external capacitors (919 only) Excellent signal quality Very low jitter Precise frequencies Minimal undershoot, ringback or overshoot Nearly perfect 50% duty cycle Four selectable clock frequencies Operates at Vcc = 3.3V Output may be disabled to save power Small 150-mil wide SOIC -8 (W8) package saves board area
DESCRIPTION
Any one of four different output frequencies can be selected via two select pins (S0, S1). The frequency multipliers are: 2, 4, 5, and 7. The PI6C919 has on-chip capacitors, eliminating the need for external capacitors at the X1, X2 pins. This reduces overall parts count and board area, and increases reliability. The OE (output enable) pin may be pulled down to disable the output buffer and save system power. The small surface-mount SOIC-8 package is ideal for compact portable equipment applications. 1 2 3 4 8 Pin Configuration OE X1 X2 GND Vcc S1 S0 CLK PinDESCRIPTION
