CY2305C/CY2309C, 3.3 V Zero Delay Clock Buffer | Cypress Semiconductor
CY2305C/CY2309C, 3.3 V Zero Delay Clock Buffer
3.3 V Zero Delay Clock Buffer
10 MHz to 100–133 MHz operating range
Zero input and output propagation delay
Multiple low skew outputs
One input drives five outputs (CY2305C)
One input drives nine outputs, grouped as 4 + 4 + 1 (CY2309C)
50 ps typical cycle-to-cycle jitter (15 pF, 66 MHz)
Test mode to bypass phase locked loop (PLL) (CY2309C) only
Available in space saving 16-pin 150 Mil small outline integrated circuit (SOIC) or 4.4 mm thin shrunk small outline package (TSSOP) packages (CY2309C), and 8-pin, 150 Mil SOIC package (CY2305C)
3.3 V operation
Commercial, industrial and automotive-A flows available
The CY2305C and CY2309C are die replacement parts for CY2305 and CY2309.
The CY2309C is a low-cost 3.3 V zero delay buffer designed to distribute high speed clocks and is available in a 16-pin SOIC or TSSOP package. The CY2305C is an 8-pin version of the CY2309C. It accepts one reference input and drives out five low skew clocks. The -1H versions of each device operate up to 100–133 MHz frequencies and have higher drive than the -1 devices. All parts have on-chip phase locked loops (PLLs) which lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad.
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
