Low Skew, 1-to-16  
LVCMOS/LVTTL Clock Generator  
87016  
DATASHEET  
GENERAL DESCRIPTION  
FEATURES  
The 87016 is a low skew, 1:16 LVCMOS/LVTTL Clock Generator. • Sixteen LVCMOS/LVTTL outputs (4 banks of 4 outputs)  
The device has 4 banks of 4 outputs and each bank can be  
• Selectable differential CLK1, nCLK1 or  
independently selected for ÷1 or ÷2 frequency operation. Each  
LVCMOS clock input  
bank also has its own power supply pins so that the banks can  
operate at the following different voltage levels: 3.3V, 2.5V, and  
1.8V.The low impedance LVCMOS/LVTTL outputs are designed  
to drive 50Ω series or parallel terminated transmission lines.  
CLK1, nCLK1 pair can accept the following differential input  
levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL  
• CLK0 supports the following input types:  
LVCMOS, LVTTL  
The divide select inputs, DIV_SELA:DIV_SELD, control the  
output frequency of each bank. The output banks can be  
independently selected for ÷1 or ÷2 operation.The bank enable  
inputs, CLK_ENA:CLK_END, support enabling and disabling  
each bank of outputs individually. The CLK_ENA:CLK_END  
circuitry has a synchronizer to prevent runt pulses when  
enabling or disabling the clock outputs. The master reset  
input, nMR/OE, resets the ÷1/÷2 flip flops and also controls the  
active and high impedance states of all outputs. This pin has  
an internal pull-up resistor and is normally used only for test  
purposes or in systems which use low power modes.  
• Maximum output frequency: 250MHz  
• Independent bank control for ÷1 or ÷2 operation  
• Independent output bank voltage settings for 3.3V, 2.5V,  
or 1.8V operation  
• Asynchronous clock enable/disable  
• Output skew: 170ps (maximum)  
• Bank skew: 30ps (maximum)  
The 87016 is characterized to operate with the core at  
3.3V and the banks at 3.3V, 2.5V, or 1.8V. Guaranteed  
bank, output, and part-to-part skew characteristics make  
the 87016 ideal for those clock applications demanding  
well-defined performance and repeatability.  
• Part-to-part skew: 750ps (maximum)  
• 3.3V core, 3.3V, 2.5V, or 1.8V output operating supply  
• 0°C to 85°C ambient operating temperature  
• Available in lead-free RoHS compliant package
