PI6C9910

Zero-Delay Clock Buffer

Features

Description

Zero input to output delay

Eight clock copies from one clock input

15 - 80 MHz output operation

Fifty percent duty cycle

The PI6C9910 is a low-skew clock driver designed to simplify

clockdistributioninsystemsrequiringnearsynchronousclocks. A

typical application is in SDRAM modules. Each of the eight

outputs (Q0-Q7) can drive individual 50Ω transmission lines with

minimal distortion or skew, and full 5V swing.

Low skew (< 250ps typ.)

An on-chip phase-locked loop (PLL) synchronizes the feedback

(FB)tothereference(REF)input, achievingzero-delaybuffered

outputs.

V = 5.0V +/- 10%, T = 0° to 70°

Low jitter (< 250 ps cycle to cycle), < 60ps RMS

Low noise unbalanced drive outputs (PI6C9910-5)

Low noise balanced drive outputs (PI6C9910A)

FB pin allows for generation of eight synchronous clock copies

whose frequency is a multiple of a lower frequency REF input.

CompatiblewithCypressCY7B9910-5

The voltage-controlled oscillator (VCO) frequency is determined

by the filtered ouput coming from the Phase/Frequency Detector.

The frequency select (FS) input sets the VCO operating range.

Test Mode

PI6C9910-5 has unbalanced output drivers (TTL), and is fully

compatiblewiththeCypressCY7B9910-5.ThePI6C9910Afeatures

balanced-drive outputs (CMOS) for improved rise/fall time

symmetry.

In normal operation the TEST pin is tied to ground. For testing

purposes it can have a removable jumper to ground or a 100Ω

pull-down resistor. When the TEST pin is driven HIGH, the VCO

output is disconnected, and all eight outputs (Q0-Q7) are directly

driven from the REF input.

The FS and TEST inputs have internal pull-up resistors.
