2 / 13 page SL28PCIe16 DOC#: SP-AP-0790 (Rev. 0.3) Page 2 of 12 32-QFN Pin Definitions EProClock® Programmable Technology EProClock® is the world’s first non-volatile programmable clock. The EProClock® technology allows board designer to promptly achieve optimum compliance and clock signal integrity; historically, attainable typically through device and/or board redesigns. EProClock® technology can be configured through SMBus or hard coded. Features: - > 4000 bits of configurations - Can be configured through SMBus or hard coded - Custom frequency sets - Differential skew control on true or compliment or both - Differential duty cycle control on true or compliment or both - Differential amplitude control - Differential and single-ended slew rate control - Program Internal or External series resistor on single-ended clocks - Program different spread profiles - Program different spread modulation rate Pin No. Name Type Description 1 VDD_SRC PWR 3.3V Power Supply 2 VDD_SRC PWR 3.3V Power Supply 3 NC NC No Connect. 4 VSS GND Ground 5 VSS GND Ground 6 SRC0 O, DIF 100MHz True differential serial reference clock 7 SRC0# O, DIF 100MHz Complement differential serial reference clock 8 VDD_SRC PWR 3.3V Power Supply 9 SRC1 O, DIF 100MHz True differential serial reference clock 10 SRC1# O, DIF 100MHz Complement differential serial reference clock 11 SRC2 O, DIF 100MHz True differential serial reference clock 12 SRC2# O, DIF 100MHz Complement differential serial reference clock 13 VSS_SRC GND Ground 14 VDD_SRC PWR 3.3V Power Supply 15 SRC3# O, DIF 100MHz Complement differential serial reference clock 16 SRC3 O, DIF 100MHz True differential serial reference clock 17 SRC4# O, DIF 100MHz Complement differential serial reference clock 18 SRC4 O, DIF 100MHz True differential serial reference clock 19 VDD_SRC PWR 3.3V Power Supply 20 SRC5# O, DIF 100MHz Complement differential serial reference clock 21 SRC5 O, DIF 100MHz True differential serial reference clock 22 VSS_SRC GND Ground 23 SCLK I SMBus compatible SCLOCK 24 SDATA I/O SMBus compatible SDATA 25 XOUT O 25.00MHz Crystal output, Float XOUT if using only CLKIN (Clock input) 26 XIN / CLKIN I 25.00MHz Crystal input or 3.3V, 25MHz Clock Input 27 VSS_CORE GND Ground 28 NC NC No Connect. 29 VDD_CORE PWR 3.3V Power Supply 30 VDD_SRC PWR 3.3V Power Supply 31 NC NC No Connect. 32 VSS_SRC GND Ground |
