PI6C2408 3.3V 4+4 Ouptut Zero-delay Clock Driver Features Description ÎÎMaximum rated frequency: 140 MHz The PI6C2408 is a PLL-based, zero-delay buffer, with the ability to distribute eight outputs of up to 140MHz at 3.3V. Two banks of four outputs exist, and, depending on product option ordered, can supply either reference frequency, prescaled half frequency, or multiplied 2x or 4x input clock frequencies. The PI6C2408 family has a power-sparing feature: when input SEL2 is 0, the component will 3-state one or both banks of outputs depending on the state of input SEL1. A PLL bypass test mode also exists. This product line is available in high-drive and industrial environment versions. ÎÎLow cycle-to-cycle jitter ÎÎInput to output delay, less than 150ps ÎÎExternal feedback pin allows outputs to be synchronized to the clock input ÎÎ5V tolerant CLKIN input ÎÎOperates at 3.3V VDD ÎÎ Test mode allows bypass of the PLL for system testing purposes (e.g., IBIS measurements) An external feedback pin is used to synchronize the outputs to the input; the relationship between loading of this signal and the other outputs determines the input-output delay. ÎÎClock frequency multipliers ½x to 4x dependent on option ÎÎPackaging (Pb-free and Green available): The PI6C2408 is characterized for both commercial and industrial operation. àà 16-pin, 150-mil SOIC (W) àà 16-pin 173-mil TSSOP (L) Block Diagram FB_IN CLKIN ÷2 Pin Configuration PLL OUTA1 MUX Option (-3, -4) SEL1 SEL2 OUTA3 OUTA4 Decode Logic ÷2 16 1 15 2 14 3 4 16-Pin 13 5 W, L 12 11 6 10 7 9 8 FB_IN OUTA4 OUTA3 VDD GND OUTB4 OUTB3 SEL1 OUTB3 PI6C2408 (-1, -1H, -2, -3, -4) PLL OUTB1 OUTB2 Option (-2, -3) FB_IN CLKIN CLKIN OUTA1 OUTA2 VDD GND OUTB1 OUTB2 SEL2 OUTA2 OUTB4 OUTA1 MUX OUTA2 OUTA3 SEL2 SEL1 OUTA4 Decode Logic ÷2 PI6C2408-6 MUX OUTB1 OUTB2 OUTB3 OUTB4 11-0005 1 www.pericom.com PS8589L 04/30/10 PI6C2408 3.3V 4+4 Ouptut Zero-delay Clock Driver Input Select Decoding for PI6C2408 (-1, -1H,-4) SEL2 SEL1 OUTA [1-4] OUTB [1-4] Output Source PLL 0 0 3-State 3-State PLL OFF 0 1 PLL 3-State PLL ON 1 0 CLKIN CLKIN CLKIN OFF 1 1 PLL PLL PLL ON Input Select Decoding for PI6C2408 (-2,-3) SEL2 SEL1 OUTA [1-4] OUTB [1-4] Output Source PLL 0 0 3-State 3-State PLL OFF 0 1 PLL 3-State PLL ON 1 0 CLKIN CLKIN/2 CLKIN OFF 1 1 PLL PLL PLL ON Input Select Decoding for PI6C2408-6 SEL2 SEL1 OUTA [1-4] OUTB [1-4] Output Source PLL 0 0 3-State 3-State PLL OFF 0 1 CLKIN CLKIN/2 CLKIN OFF 1 0 PLL PLL PLL ON 1 1 PLL PLL/2 PLL ON PI6C2408 Configurations Device Feedback From OUTA [1-4] Frequency OUTB [1-4] Frequency PI6C2408-1 OUTA or OUTB CLKIN CLKIN PI6C2408-1H OUTA or OUTB CLKIN CLKIN PI6C2408-2 OUTA CLKIN CLKIN/2 PI6C2408-2 OUTB 2X CLKIN CLKIN PI6C2408-3 OUTA 2X CLKIN CLKIN or CLKIN(1) PI6C2408-3 OUTB 4X CLKIN 2X CLKIN PI6C2408-4 OUTA or OUTB 2X CLKIN 2XCLKIN PI6C2408-6 OUTA CLKIN CLKIN or CLKIN/2 PI6C2408-6 OUTB CLKIN or 2X CLKIN CLKIN Note: 1.
