M9999-012208 hbwhelp@micrel.com or (408) 955-1690 PIN DESCRIPTIONS Internal Pin Number Pin Name I/O Type P/U Pin Function 5, 6 LVDS_CLKA Input LVDS 3.5kΩ Differential clock input selected by CLK_SEL1, SEL1 and /LVDS_CLKA Pull-up SEL2. Can be left floating if not selected. Floating input, if See Fig. 2 selected produces an indeterminate output. Has internal 100Ω termination. 2, 3 LVDS_CLKB Input LVDS 3.5kΩ Differential clock input selected by CLK_SEL1, SEL1 and /LVDS_CLKB Pull-up SEL2. Can be left floating if not selected. Floating input, if See Fig. 2 selected produces an indeterminate output. Has internal 100Ω termination. 8, 9 LVPECL_CLKA Input LVPECL 75kΩ Differential clock input selected by CLK_SEL1, SEL1 /LVPECL_CLKA pull-down and SEL2. Can be left floating. Floating input, if selected See Fig. 1 produces a LOW at output. Requires external termination. 12, 13 LVPECL_CLKB Input LVPECL 75kΩ Differential clock input selected by CLK_SEL2, SEL1 /LVPECL_CLKB pull-down and SEL2. Requires external termination. See Fig. 1 7 CLK_SEL1 Input LVTTL/ 11kΩ Selects LVDS_CLKA input when LOW and CMOS Pull-up LVPECL_CLKA input when HIGH. 14 CLK_SEL2 Input LVTTL/ 11kΩ Selects LVDS_CLKB input when LOW and CMOS Pull-up LVPECL_CLKB input when HIGH. 16 SEL1 Input LVTTL/ 11kΩ Selects input source CLKA when LOW and CLKB CMOS Pull-up when HIGH for outputs Q0 – Q9 and /Q0 – /Q9. 1 SEL2 Input LVTTL/ 11kΩ Selects input source CLKA when LOW and CLKB CMOS Pull-up when HIGH for outputs Q10 – Q19 and /Q10 – /Q19. 11 OE1 Input LVTTL/ 11kΩ Enable input synchronized internally to prevent output CMOS Pull-up glitches or runt pulses. 15 OE2 Input LVTTL/ 11kΩ Enable input synchronized internally to prevent output CMOS Pull-up glitches or runt pulses. 4 VCCI Power Core VCC connected to 3.3V supply. Not connected to VCCO internally. Connected to VCCO on PCB. Bypass with 0.1µF in parallel with 0.01µF low ESR capacitors as close to VCC pins as possible. 17, 32, 40, VCCO Power Output buffer VCC connected to 3.3V suppy. Not connected 41, 49, 64 to VCCI internally. Connected to VCCI on PCB. Bypass with 0.1µF in parallel with 0.01µF low ESR capacitors as close to VCC pins as possible. 10 GNDI Power Core ground not connected to GNDO internally. To be connected to GNDO on PCB. 33, 48 GNDO Power Output buffer ground not connected to GNDI internally. To be connected to GNDI on PCB. 63, 61, 59, 57, 55 Q0 – Q9 Output LVDS Differential clock outputs from CLKA when SEL1 = LOW 53, 51, 47, 45, 43 and from CLKB when SEL1 = HIGH. Q outputs are static when OE1 = LOW. Unused output pair must be terminated with 100Ω to maintain low jitter and skew. 62, 60, 58, 56, 54 /Q0 – /Q9 Output LVDS Differential clock outputs (complement) from CLKA when 52, 50, 46, 44, 42 SEL1 = LOW and from CLKB when SEL1 = HIGH. /Q outputs are static HIGH when OE1 = LOW. Unused output pairs must be externally terminated with 100Ω to maintain low jitter and skew. 39, 37, 35, 31, 29 Q10 – Q19 Output LVDS Differential outputs from CLKA when SEL2 = LOW and 27, 25, 23, 21, 19 from CLKB when SEL2 = HIGH. Q outputs are static LOW when OE2 = LOW. Unused output pairs must be externally terminated with 100Ω to maintain low jitter and skew. |
