CY2SSTV857-27

Differential Clock Buffer/Driver

DDR333/PC2700-Compliant

Description

Features

• Operating frequency: 60 MHz to 200 MHz

• Supports 266, 333-MHz DDR SDRAM

• 10 differential outputs from 1 differential input

• Spread-Spectrum-compatible

• Low jitter (cycle-to-cycle): < 75

• Very low skew: < 100 ps

• Power management control input

• High-impedance outputs when input clock < 10 MHz

• 2.5V operation

The CY2SSTV857-27 is a high-performance, low-skew,

low-jitter zero-delay buffer designed to distribute differential

clocks in high-speed applications. The CY2SSTV857-27

generates ten differential pair clock outputs from one differ-

ential pair clock input. In addition, the CY2SSTV857-27

features differential feedback clock outputs and inputs. This

allows the CY2SSTV857-27 to be used as a zero-delay buffer.

When used as a zero-delay buffer in nested clock trees, the

CY2SSTV857-27 locks onto the input reference and translates

with near-zero delay to low-skew outputs.

• Pin-compatible with CDC857-2 and -3

• 48-pin TSSOP package

• Industrial temp. of –40° to +85°C

• Conforms to JEDEC DDR specification
