Low Jitter and Skew 10 to 140 MHz Zero Delay Buffer (ZDB)
- 140 ps-max c-c-j at 66 MHz
- 14 mA-max at 66MHz
- 26 mA-max at 133 MHz
Description
The SL2305 is a low skew, low jitter and low power Zero
Delay Buffer (ZDB) designed to produce up to five (5) clock
outputs from one (1) reference input clock for high speed
clock distribution applications. The product has an on-chip
PLL which locks to the input clock at CLKIN and receives its
feedback internally from the CLKOUT pin.
The SL2305 is available with two (2) drive strength versions.
The -1 is the standard-drive version and -1H is the high-
drive version.
The SL2305 high-drive version operates up to 140MHz and
the standard drive version -1 operates up to 100.
at CLKIN is DC (0 to VDD). In this power-down state all five
(5) outputs are tri-stated and the PLL is turned off leading to
less than 12μA-max of power supply current draw.
Benefits
The SL2305 enter into Power-Down (PD) mode if the input
• Up to five (5) distribution of input clock
• Standard and High-Drive levels to control impedance
• Low jitter and skew
• Low power dissipation
• Low cost
level, frequency range and EMI
