CY2SSTV16857  
14-Bit Registered Buffer PC2700-/PC3200-Compliant  
When RESET is LOW, the differential input receivers are  
disabled, and undriven (floating) data, clock, and REF voltage  
inputs are allowed. In addition, when RESET is LOW, all  
registers are reset and all outputs force to the LOW state. The  
LVCMOS RESET input must always be held at a valid logic  
HIGH or LOW level.  
Features  
• Differential Clock Inputs up to 280 MHz  
• Supports LVTTL switching levels on the RESET pin  
• Output drivers have controlled edge rates, so no  
external resistors are required  
To ensure defined outputs from the register before a stable  
clock has been supplied, RESET must be held in the LOW  
state during power-up.  
• Two KV ESD protection  
• Latch-upperformanceexceeds 100 mA: JESD78, Class II  
In the DDR registered DIMM application, RESET is specified  
to be completely asynchronous with respect to CLK and CLK.  
Therefore, no timing relationship can be guaranteed between  
the two. When entering reset, the register will be cleared and  
the outputs will be driven LOW quickly, relative to the time to  
disable the differential input receivers, thus ensuring no  
glitches on the output. However, when coming out of reset, the  
register will become active quickly, relative to the time to  
enable the differential input receivers. As long as the data  
inputs are low, and the clock is stable during the time from the  
LOW-to-HIGH transition of RESET until the input receivers are  
fully enabled, the design must ensure that the outputs will  
remain LOW.  
• Conforms to JEDEC STD (JESD82-3) for buffered DDR  
DIMMs  
• 48-pin TSSOP  
Description  
This 14-bit registered buffer is designed specifically for 2.3V to  
2.7V VDD operation and is characterized for operation from  
0°C to + 85°C.  
All inputs are compatible with the JEDEC Standard for  
SSTL_2, except the LVCMOS reset (RESET) input. All outputs  
are SSTL_2, Class II-compatible.  
The SSTV16857 operates from a differential clock (CLK and  
CLK). Data is measured at the crossing of CLK going HIGH,  
and CLK going LOW.
