CY2DL1510 1:10 Differential LVDS Fanout Buffer Features ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Functional Description The CY2DL1510 is an ultra-low noise, low-skew, low-propagation delay 1:10 differential LVDS fanout buffer targeted to meet the requirements of high-speed clock distribution applications. The on-chip 100-Ω input termination resistor reduces board component count, while the synchronous clock enable function ensures glitch-free output transitions during enable and disable periods. The device has a fully differential internal architecture that is optimized to achieve low-additive jitter and low-skew at operating frequencies of up to 1.5 GHz. Low-voltage differential signal (LVDS) input with on-chip 100-Ω input termination resistor Ten differential LVDS outputs 40-ps maximum output-to-output skew 600-ps maximum propagation delay 0.11-ps maximum additive RMS phase jitter at 156.25 MHz (12-kHz to 20-MHz offset) Up to 1.5-GHz operation Synchronous clock enable function 32-pin thin quad flat pack (TQFP) package 2.5-V or 3.3-V operating voltage[1] Commercial and industrial operating temperature range Logic Block Diagram Q0 Q0# Q1 Q1# VDD VSS Q2 Q2# Q3 Q3# IN IN# 100 Q4 Q4# Q5 Q5# VDD 100k Q D CLK_EN Q6 Q6# Q7 Q7# VBB Q8 Q8# Q9 Q9# Note 1.
