The receive section DCC (RSD) signal contains the

section data communications channel (D1-D3)

The receive section DCC clock (RSDCLK) is used

to clock out the section DCC.

RSDCLK is a 192 kHz clock used to update the

RSD output. RSDCLK is generated by gapping a

216 kHz clock.

The transmit section DCC (TSD) signal contains the

section data communications channel (D1-D3).

TSD is sampled on the rising edge of TSDCLK.

The transmit section DCC clock (TSDCLK) is used

to clock in the section DCC.

TSDCLK is a 192 kHz clock used to sample the

TSD input. TSDCLK is generated by gapping a 216

kHz clock.

The receive line DCC (RLD) signal contains the line

data communications channel (D4-D12).

The receive line DCC clock (RLDCLK) is used to

clock out the line DCC.

RLDCLK is a 576 kHz clock used to update the

RLD output. RLDCLK is generated by gapping a

2.16 MHz clock.

The transmit line DCC (TLD) signal contains the

line data communications channel (D4-D12).

TLD is sampled on the rising edge of TLDCLK.

The transmit line DCC clock (TLDCLK) is used to

clock in the line DCC.

TLDCLK is a 576 kHz clock used to sample the

TLD input. TLDCLK is generated by gapping a 2.16

MHz clock.
