The CSPT857CNLGI8 is a PLL-based differential clock driver designed for DDR SDRAM applications, capable of distributing one differential clock input to ten differential output pairs. It operates within a frequency range of 60MHz to 220MHz and features low skew of less than 100ps for PC1600 to PC2700 and less than 75ps for PC3200. The device also exhibits low jitter, with specifications of less than 75ps for PC1600 to PC2700 and less than 50ps for PC3200. This clock driver supports both commercial (0¬8C to +70¬8C) and industrial (-40¬8C to +85¬8C) temperature ranges and requires a supply voltage of 2.5V to 2.6V, depending on the DDR speed. It includes a CMOS control signal input, a test mode for enabling buffers while disabling the PLL, and a low current power-down mode that reduces consumption to less than 200OºA when the input frequency drops below approximately 20MHz. The CSPT857CNLGI8 is available in multiple package options, including 48-pin TSSOP, 40-pin VFQFPN, and 56-pin VFBGA, making it suitable for various design implementations in both module assemblies and motherboard solutions.
