LOW SKEW  
IDT59920A  
PLL CLOCK DRIVER  
TURBOCLOCK™ JR.  
FEATURES:  
DESCRIPTION:  
• Eight zero delay outputs  
The IDT59920A is a high fanout phase lock loop clock driver in-  
tended for high performance computing and data-communications appli-  
cations. The IDT59920A has CMOS outputs.  
• Selectable positive or negative edge synchronization  
• Synchronous output enable  
• Output frequency: 15MHz to 100MHz  
• CMOS outputs  
• 3 skew grades:  
IDT59920A-2: tSKEW0<250ps  
The IDT59920A maintains Cypress CY7B9920 compatibility while  
providing two additional features: Synchronous Output Enable (GND/  
sOE), and Positive/Negative Edge Synchronization (VDDQ/PE). When  
the GND/sOE pin is held low, all outputs are synchronously enabled  
(CY7B9920 compatibility). However, if GND/sOE is held high, all out-  
puts except Q2 and Q3 are synchronously disabled.  
IDT59920A-5: tSKEW0<500ps  
IDT59920A-7: tSKEW0<750ps  
• 3-level inputs for PLL range control  
• PLL bypass for DC testing  
• External feedback, internal loop filter  
• 46mA IOL high drive outputs  
• Low Jitter: <200ps peak-to-peak  
• Outputs drive 50terminated lines  
• Pin-compatible with Cypress CY7B9920  
• Available in SOIC package  
Furthermore, when the VDDQ/PE is held high, all outputs are synchro-  
nized with the positive edge of the REF clock input (CY7B9920 compat-  
ibility). When VDDQ/PE is held low, all outputs are synchronized with the  
negative edge of REF.  
The FB signal is compared with the input REF signal at the phase  
detector in order to drive the VCO. Phase differences cause the VCO of  
the PLL to adjust upwards or downwards accordingly.  
An internal loop filter moderates the response of the VCO to the  
phase detector. The loop filter transfer function has been chosen to  
provide minimal jitter (or frequency variation) while still providing accu-  
rate responses to input frequency changes.
