DDR SDRAM MUX

GENERAL DESCRIPTION

FEATURES

The ICS83840B is a DDR SDRAM MUX and is

• 40 low skew single-ended DIMM ports

• 4 SSTL-2 compatible enable inputs

• Maximum Switching Speed: 3ns

• Output skew: 120ps (maximum)

• Bank skew: 60ps (maximum)

• r_on= 8Ω (typical)

ICS

a member of the HiPerClockS™ family of High

Performance Clock Solutions from ICS.The de-

vice has 10 Host Lines and each host line can

be passed to 4 Data Ports.The 10 channels are

allocated as follows in the DDR SDRAM appli-

HiPerClockS™

cation: 8 data lines, 1 strobe line and 1 DQm line. The Host/

Data Ports are compatible with single-ended SSTL-2 and the

device operates from a 2.5V supply.

• Full 2.5V supply modes

Guaranteed low output skew makes the ICS83840B ideal • 0°C to 70°C ambient operating temperature

for demanding applications which require well defined per-

formance and repeatability.

• Pin compatible with the CBTV4010
