CY2DL1510 1:10 Differential LVDS Fanout Buffer Features Functional Description ■ 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) 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. ■ 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 Q2 Q2# VSS Q3 Q3# IN IN# Q4 Q4# 100 Q5 Q5# VDD Q 100k CLK_EN Q6 Q6# D Q7 Q7# VBB Q8 Q8# Q9 Q9# Note 1.
