SL2309 Low Jitter and Skew 10 to 140 MHz Zero Delay Buffer (ZDB)
The SL2309 is a low skew, low jitter and low power Zero Delay Buffer (ZDB) designed to produce up to nine (9) 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 SL2309 has two (2) clock driver banks each with four (4) clock outputs. These outputs are controlled by two (2) select input pins S1 and S2. When only four (4) outputs are needed, four (4) bank-B output clock buffers can be tri-stated to reduce power dissipation and jitter. The select inputs can also be used to tri-state both banks A and B or drive them directly from the input bypassing the PLL and making the product behave like a Non-Zero Delay Fanout Buffer (NZDB).
The high-drive(-1H)version operates up to 140MHz and low drive(-1)version operates up to 100MHzat 3.3V.
