Description : 100MHZ 2-DIMM SDRAM BUFFER FOR NOTEBOOK

 GENERAL DESCRIPTION
The W83L177R is a 10 outputs SDRAM clock buffer for 2-DIMMs models incorporate with W83L197R-16 which is the clock synthesizer especially for the 100MHz models such as Intel BX chipsets.(Refer the datasheet fo Winbond W83L197R-16)
The W83L177R receives the clock from chipset by the Buffer_In pin and provides almost zerodelay (less than 4ns propagation delay) SDRAM buffer outputs for the 10 SDRAM clocks which are synchronous with the CPU clock outputs priovided by W83L197R-16. The clock skew between any two clock outputs is less than 250ps and the output buffer impedance is about 15 ohms.
The W83L177R also provides I2C serial bus interface to program the registers to enable or disable each SDRAM clock outputs.

PRODUCT FEATURES
●  10 SDRAM clocks for 2-DIMMs
●  Clock skew less than 250ps
●  Almost none delay Buffer-in controlling SDRAM clocks(< 4ns propagation delay)
●  I2C 2-wire serial interface
●  Programmable registers to enable/stop each output
●  Incorporate with W83L197R-16
●  28pin-SOP package (209mil)

Description : High Performance SDRAM Controller for 32-bit and 64-bit Embedded Processors

The V380SDC High Performance SDRAM Controller provides all aspects of SDRAM control for high performance embedded systems. The V380SDC enables system designers to replace many lower integration support components with a single, high-integration device. This saves design time, board space, and manufacturing cost.
The V380SDC from V3 Semiconductor provides the necessary (Enhanced) SDRAM access protocol and bus timing resources to work with the latest (E)SDRAM devices. The processor interface on the V380SDC implements the bus protocol of many popular RISC CPUs (AM29030/40, PowerPC 401 Gx, IDT 79RC32364, i960 Cx/Hx/Jx/Rx/Vx, M68040, 68K/ColdFire, PowerPC 750/60x). The V380SDC is also fully compatible with the EPC family of PCI bridges available from V3 Semiconductor.
