Clocking Modes and Timing Adjustments
(continued)
Contra-Directional Clocking Mode
(CLKMODE, PHADJ[1:0])
In the contra-directional clocking mode (CLKMODE = 1), the data is sampled with the internal 2.5 GHz clock at the
time of the falling edge of CK155P (see Figure 8 on page 19 for timing details). The device sends a 155 MHz clock
with one of four user-selectable phases out to the upstream device for clocking the data toward the device. The
user can program PHADJ[1:0] to adjust the phase of CK155 as a function of PWB layout and upstream device
propagation delay in order to meet the setup and hold time of the 155 Mbits/s data to the device. With a
PHADJ[1:0] = [11], the data is sampled by the internal CK2G5 clock at the falling edge of CK155P. PHADJ[1:0]
changes the phase of the CK155P clock without changing the input data sampling time. PHADJ[1:0] setting infor-
mation is given in Table 7, and the phase relationship of CK155 for each PHADJ[1:0] setting is shown in Figure 6.
