PI6CX100-27WE

Programmable Timers And Oscillators Overview

The PI6CX100-27WE is a 3.3V Voltage Controlled Crystal Oscillator (VCXO) designed for set-top box applications. It operates with an external 27 MHz quartz crystal and accepts a 0 to 3.3V tuning voltage input to pull the output frequency by ±120ppm, providing a total pull range of 240ppm. The device delivers CMOS-level clock outputs with a typical supply current of 5mA and supports cycle-to-cycle jitter of 50ps at a 15pF load. It is housed in an 8-pin SOIC (W) package.

Programmable Timers And Oscillators Applications

• Set-Top Box systems

Programmable Timers And Oscillators Procurement Notes

Verify the component origin as Pericom Semiconductor Corporation, now part of Diodes Incorporated. Confirm the specific ordering suffix 'E' indicates Pb-free and Green packaging status. Ensure the external crystal specifications match the datasheet requirements for optimal performance.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-cost, fixed-frequency 27 MHz VCXO is required for set-top boxes. Ensure the design accommodates an external AT-cut crystal with specified ESR and load capacitance. Verify that the application requires a ±120ppm pull range and 3.3V logic compatibility.

Programmable Timers And Oscillators Part Context

This part belongs to the PI6CX100 series of voltage-controlled crystal oscillators. It is manufactured by Pericom Semiconductor Corporation, which has been acquired by Diodes Incorporated. The device is distinct from buffer or generator families due to its integrated VCXO architecture requiring external resonators.
