The design of the HDMP-0421
allows for placement of the CDR
at one of two locations with
respect to a hard disk slot. For
example, if the BYPASS[0]– pin
is HIGH and hard disk slot A is
connected to PBC cell 1, the CDR
function will be performed before
entering the hard disk at slot A
Figure 2. Timing Waveforms.
Figure 1. Block Diagram of HDMP-0421.
(Figure 4). To achieve a CDR
function after slot A, the
BYPASS[1]– pin must be HIGH
and hard disk slot A must be
connected to PBC cell 0
(Figure 5). Table 2 shows both
possible connections. In both
cases, a Signal Detect (SD) pin
shows the status of the signal at
the incoming cable. The
recommended method of setting
the BYPASS[i]– pins HIGH is to
drive them with a high-
impedence signal. Internal pull-
up resistors will force the
BYPASS[I]– pins to V
