miClockManagement Clock Fanout Buffer Product Preview Microsemi's portfolio of miClockBufferTM and miSmartBufferTM clock fanout buffers are synergistic with Microsemi's industry-leading timing portfolio--when combined with miClockSynthTM synthesizers, they can create a simplified, more reliable, and low-cost complete clock tree that replaces many on-board multipliers, synthesizers, and oscillators. miClockBuffer ZL402xx Family Microsemi's miClockBuffer ZL402xx family of buffers offers six fanout combinations with LVPECL or LVDS output types and internal and external terminations. The miClockBuffer and miSmartBuffer ZL4023x and ZL4024x family of devices are offered in a variety of input and output configurations including LVPECL, LVDS, HCSL, and LVCMOS. The portolio also includes the miSmartBuffer ZL4025x family of devices, differentiated from traditional fanout buffers by compelling features including dividers and configurable outputs. * LVPECL or LVDS outputs Applications * Clock rates up to 750 MHz * LVPECL, LVDS, CML, HCSL or LVCMOS inputs with devices with internal or external input termination available * Six fanout combinations--1:2, 1:4, 1:6, 1:8, 2:6, and 2:8 * Ultra-low additive jitter (as low as 39 fs RMS) miClockBuffer ZL4023x/ZL4024x Family * Up to three inputs/crystal input/inverted mesa/high-speed crystal * Clock signal fanout, format conversion, frequency division, and skew adjustment in a wide variety of equipment types, including processors, NPUs, FPGAs, 10G CDRs, high-speed ADCs and DACs, PCIe interface devices, Ethernet switches, and PHYs * Up to 10 LVPECL/LVDS/HCSL or 10 LVCMOS outputs * Clock trees for optical, OTN, SONET, SDH, WDM, storage, networking, and broadcast video applications * miSmartbuffer ZL4023x/ZL4024x family also adds a serial port interface and integer dividers on the LVCMOS outputs IEEE 1588/SyncE Clock Tree miSmartBuffer ZL4025x Family I2C_A TXCO OSCI HPOUT4/5 125 MHz DPLL0 (SyncE clock domain) HPOUT0/1 125 MHz ZL40200 1:2 buffer (SyncE clock domain) I2C_B ZL40200 1:2 buffer (1588 clock domain) I2C_C DPLL1 (1588 clock domain) 125 MHz 156.25 MHz 25 MHz 125 MHz OR 156.25 MHz 1 pps 156.25 MHz I2C_D REFIN0/1 REFIN2/3 HPOUT6/7 156.25 MHz ZL40202 1:4 buffer (SyncE clock domain) ZL30702 HPOUT2/3 REFIN8 REFIN9 REF_CLK [0:7] ZL40252 10 output buffer (SyncE clock domain) REF_CLK [8:15] ZL40252 10 output buffer (1588 clock domain) PTP_CLK [0:7] ZL40252 10 output buffer (1588 clock domain) PTP_CLK [8:15] PTP_CLK [1:4] * 4 flexible input clocks allow interfacing to a wide variety of devices--crystal/XO, two differential/ CMOS, and one single-ended/CMOS * Frequency conversion--each output has independent divider * Improve alignment and skew with per-output skew adjustment, per-output enable/disable and glitchless start/stop * Easily interface--each output configurable as LVDS, LVPECL, HCSL, 2x CMOS, or HSTL 25 MHz TX Ref REFIN4/5 REFIN6/7 ZL40252 10 output buffer (SyncE clock domain) * Low skew and ultra-low additive jitter, as low as 25 fs RMS (12 kHz to 20 mHz) HPOUT8/9 GPOUT1 25 MHz ZL40202 1:4 buffer (1588 clock domain) ZL40200 1:2 buffer 156.25 MHz (SyncE clock domain) 125 MHz OR 1 pps ZL40202 1:4 buffer (1588 clock domain) 25 MHz RX Ref 25 MHz to FPGA FPGA [0:1] SYNC [0:3] Benefits * Reduces BOM cost and board space--enables designers to create larger clock trees or simplify small clock trees, leading to significant cost savings Availability and Support Microsemi miClockManagement products are in volume production.
