PCB replication case in China
The three-layer core switch exchange board is a typical high-speed board. The PCB replication department of OROD Technology analyzes the data in detail to calculate the timing. HSPICE simulates the wiring rules of 1.25G signals and 3.125G signals. Pre-simulation determines the routing topology of RLDRAM, DDRII SDRAM, and TCAM, and post-simulation confirms their timing. The current calculation software reasonably designs the current wiring channel. The multi-person parallel design ensures single-board progress.
OROD Technology’s PCB replication department uses the BCM56601 chipset solution. It is with RLDRAM, DDRII SDRAM, and TCAM, with strict timing requirements; 3.125G pairs of high-speed signals on the board. Forty-eight pairs of 1.25G signals, each pair is 13 inches in length; There are many kinds of power sources; there are eight kinds of currents above six amps, a large number of phase-locked loops; the number of single-board PINs is more than 25,000, and a lot of network rules.
