datasheet low-cost, 3.3v zero delay buffer mpc962305 nrnd mpc962305 revision 8 january 8, 2013 1 ?2013 integrated device technology, inc. the mpc962309 is a zero delay buffer designed to distribute high-speed clocks. available in a 16-pin soic or tssop package, the device accepts one reference input and drives nine low-skew clocks. the mpc962305 is the 8-pin version of the mpc962309 which drives five outputs with one reference input. the -1h versions of these devices have hi gher drive than the -1 devices and can operate up to 100/-133 mhz frequencies. these parts have on-chip plls which lock to an input clock presented on the ref pin. the pll feedback is on-chip and is obtained from the clockout pad. features ? 1:5 lvcmos zero-delay buffer (mpc962305) ? 1:9 lvcmos zero-delay buffer (mpc962309) ? zero input-output propagation delay ? multiple low-skew outputs ? 250 ps max output-output skew ? 700 ps max device-device skew ? supports a clock i/o frequency range of 10 mhz to 133 mhz, compatible with cpu and pci bus frequencies ? low jitter, 200 ps max cycle-cycl e, and compatible with pentium ? based systems ? test mode to bypass pll (mpc962309 only. see ta b l e 3 ) ? 8-pin soic or 8-pin tssop package (mpc962305);16-pin soic or 16-pin tssop package (mpc962309), all pb-free ? single 3.3 v supply ? ambient temperature range: ?40 ? c to +85 ? c ? compatible with the cy2305, cy23s05, cy2309, cy23s09 ? spread spectrum compatible ? not recommend for new designs use replacement part idt2305 ? the mpc962309 has two banks of four outputs each, which can be controlled by the select inputs as shown in ta b l e 3 . bank b can be tri-stated if all of the outputs ar e not required. select inputs also allow th e input clock to be directly applied to the outputs for chip and system testing purposes. the mpc962305 and mpc962309 plls enters a power down state w hen there are no rising edges on the ref input. during this state, all of the outputs are in tristate, the pll is turned off, and there is less than 25.0 ? a of current draw for the device. the pll shuts down in one additional case as shown in ta b l e 3 . multiple mpc962305 and mpc962309 devices can accept the same input clock and distribute it throughout the system. in this situation, the difference between the output skews of two devices will be less than 700 ps. all outputs have less than 200 ps of cycle-cycle jitter. the inpu t-to-output propagati on delay on both devi ces is guaranteed to be less than 350 ps and the output-to-output skew is guaran teed to be less than 250 ps. the mpc962305 and mpc962309 are available in two/three diff erent configurations, as shown on the ordering information page. the mpc962305-1/mpc962309-1 are the base parts. high drive versions of those devices, mpc962305-1h and mpc962309-1h, are available to provide faster rise and fall times of the base device. pentium ii is a trademark of intel corporation. mpc962305 mpc962309 ef suffix 8-lead soic package pb-free package case 751-06 ej suffix 8-lead tssop package pb-free package case 948j-01 ef suffix 16-lead soic package pb-free package case 751b-05 ej suffix 16-lead tssop package pb-free package case 948f-01 nrnd ? not recommend for new designs
