It consists of an onchip crystal oscillator, PLL, LVCMOS output buffer, and LVDS output buffers. Using a low-frequency clock (crystal or CMOS input) as a reference, the internal PLL generates a high-frequency 125MHz output clock with excellent jitter performance. Crystal Oscillator An integrated oscillator provides the low-frequency reference clock for the PLL. This oscillator requires an external crystal connected between X_IN and X_OUT. The crystal frequency is 25MHz. See the Applications Information section for more information. OSC_IN Buffer The LVCMOS OSC_IN buffer is internally biased to allow AC- or DC-coupling. This input is internally ACcoupled, and is designed to operate at 25MHz when the PLL is enabled (PLL_BP is left open). When the PLL is bypassed (PLL_BP is set low), the OSC_IN buffer can be operated from 20MHz to 320MHz. PLL The PLL takes the signal from the crystal oscillator or reference clock input and synthesizes a low-jitter, highfrequency 125MHz clock. The PLL contains a phasefrequency detector (PFD), a lowpass filter, and a voltage-controlled oscillator (VCO) that operates at 625MHz. The PLL bandwidth is tuned to 150kHz typical to optimize both phase noise and power-supply noise rejection (PSNR). The VCO output is connected to the PFD input through a feedback divider that divides the VCO frequency by 25 to lock onto the 25MHz reference clock or oscillator. To minimize the jitter induced by power-supply noise, the VCO supply (VDDA) is isolated from the core logic and output buffer supplies. Applications Information Power-Supply Filtering The MAX3677 is a mixed analog/digital IC. The PLL contains analog circuitry susceptible to random noise. To take full advantage of on-board filtering and noise attenuation, in addition to excellent on-chip power-supply rejection, this part provides a separate power-supply pin, VDDA, for the VCO circuitry. The purpose of this design technique is to ensure clean input power supply to the VCO circuitry and to improve the overall immunity to power-supply noise. Figure 4 illustrates the recommended power-supply filter network for VDDA. This network requires that the power supply is +3.3V ±5%. Decoupling capacitors should be used on all other supply pins and placed as close as possible to the pins for best performance. Crystal Input Layout and Frequency Stability The MAX3677 features an integrated on-chip crystal oscillator to minimize system implementation cost. The integrated crystal oscillator is a Pierce-type that uses the crystal in its parallel resonance mode. It is recommended to use a 25MHz crystal with a load specification of CL = 18pF. See Table 1 for the recommended crystal specifications. The crystal, trace, and two external capacitors should be placed on the board as close as possible to the X_IN and X_OUT pins to minimize the board parasitic capacitance and prevent active signals from coupling into the oscillator. +3.3V ±5% VDD 0.1μF LVDS Drivers The high-frequency outputs—Q0, Q1, Q2, Q3, Q4, Q5, and Q6—are differential LVDS buffers designed to drive 100Ω. MAX3677 10.5Ω VDDA 0.01μF 10μF LVCMOS Driver LVCMOS output Q7 is provided on the MAX3677. It is designed to drive single-ended high-impedance loads. The output specifications are only valid up to 160MHz. Figure 4.

Crystal Layout 10 ______________________________________________________________________________________ +3.3V, Low-Jitter, Precision Clock Generator with Multiple Outputs Layout Considerations The inputs and outputs are the most critical paths for the MAX3677 and great care should be taken to minimize discontinuities on these transmission lines between the connector and the IC. Here are some suggestions for maximizing the performance of the MAX3677: • An uninterrupted ground plane should be positioned beneath the clock outputs. The ground plane under the crystal should be removed to minimize capacitance. 1.4V VDD 180kΩ OSC_IN ESD STRUCTURES Figure 7. Simplified OSC_IN Pin Circuit Schematic VDDO_SE • Ground pin vias should be placed close to the IC and the input/output interfaces to allow a return current path to the MAX3677 and the receive devices. • Supply decoupling capacitors should be placed close to the supply pins, preferably on the same layer as the MAX3677. • Take care to isolate crystal input traces from the MAX3677 outputs. • The crystal, trace, and two external capacitors should be placed on the board as close as possible to the X_IN and X_OUT pins. 10Ω Q7 10Ω ESD STRUCTURES • Maintain 100Ω differential (or 50Ω single-ended) transmission line impedance into and out of the part. • Use good high-frequency layout techniques and multilayer boards with an uninterrupted ground plane to minimize EMI and crosstalk. Refer to the MAX3677 evaluation kit for more information. Exposed-Pad Package Figure 8. Simplified LVCMOS Output Circuit Schematic VDDO_DIFF VDD The exposed pad on the 32-pin TQFN package provides a very low inductance path for return current traveling to the PCB ground plane. The pad is thermal and electrical ground on the MAX3677 and must be soldered to the circuit board ground for proper electrical performance. 75kΩ Chip Information PROCESS: BiCMOS OE Package Information For the latest package outline information and land patterns . .
