2 / 16 page ICS844004-104 FEMTOCLOCK™CRYSTAL-TO-LVDS FREQUENCY SYNTHESIZER IDT™ / ICS™ LVDS FREQUENCY SYNTHESIZER 2 ICS844004AK-104 REV. A SEPTEMBER 15, 2008 Table 1. Pin Descriptions NOTE: Pulldown refers to internal input resistors. See Table 2, Pin Characteristics, for typical values. Table 2. Pin Characteristics Number Name Type Description 1, 2 Q0, nQ0 Output Differential output pair. LVDS interface levels. 3 MR Input Pulldown Active HIGH Master Reset. When logic HIGH, the internal dividers are reset causing the true outputs Qx to go low and the inverted outputs nQx to go high. When logic LOW, the internal dividers and the outputs are enabled. LVCMOS/LVTTL interface levels. 4 nPLL_SEL Input Pulldown Selects between the PLL and REF_CLK as input to the dividers. When LOW, selects PLL (PLL Enable). When HIGH, deselects the reference clock (PLL Bypass). LVCMOS/LVTTL interface levels. 5, 6, 7, 8, 15, 16, 20, 21, 28, 29 nc Unused No connect. 9VDDA Power Analog supply pin. 10, 12 F_SEL0, F_SEL1 Input Pulldown Frequency select pin. LVCMOS/LVTTL interface levels. 11 VDD Power Core supply pin. 13, 14 XTAL_OUT XTAL_IN Input Crystal oscillator interface. XTAL_IN is the input, XTAL_OUT is the output. 17, 22 GND Power Power supply ground. 18 REF_CLK Input Pulldown Single-ended reference clock input. LVCMOS/LVTTL interface levels. 19 nXTAL_SEL Input Pulldown Selects between crystal or REF_CLK inputs as the PLL Reference source. Selects XTAL inputs when LOW. Selects REF_CLK when HIGH. LVCMOS/LVTTL interface levels. 23, 24 nQ3, Q3 Output Differential output pair. LVDS interface levels. 25, 32 VDDO Power Output supply pins. 26, 27 Q2, nQ2 Output Differential output pair. LVDS interface levels. 30, 31 nQ1, Q1 Output Differential output pair. LVDS interface levels. Symbol Parameter Test Conditions Minimum Typical Maximum Units CIN Input Capacitance 4 pF RPULLDOWN Input Pulldown Resistor 51 k Ω |
