DS21348T Pin Numbering)
NAME
PIN
I/O
FUNCTION
BIS0/BIS1
32/33
I
Bus Interface Select Bits 0 and 1. Used to select bus interface
option. BIS0 = 1 and BIS1 = 1 selects hardware mode.
BPCLK
31
O
Backplane Clock. 16.384MHz output.
CES
12
I
Receive and Transmit Clock Edge Select. Selects which RCLK
edge to update RPOS and RNEG and which TCLK edge to sample
TPOS and TNEG.
0 = update RNEG/RPOS on rising edge of RCLK; sample
TPOS/TNEG on falling edge of TCLK
1 = update RNEG/RPOS on falling edge of RCLK; sample
TPOS/TNEG on rising edge of TCLK
DJA
8
I
Disable Jitter Attenuator.
0 = jitter attenuator enabled
1 = jitter attenuator disabled
EGL
1
I
Receive Equalizer Gain Limit. This pin controls the sensitivity of
the receive equalizer.
EGL
E1 (ETS = 0)
0 = -12dB (short haul)
1 = -43dB (long haul)
EGL
T1 (ETS = 1)
0 = -36dB (long haul)
1 = -30dB (limited long haul)
ETS
2
I
E1/T1 Select.
0 = E1
1 = T1
HBE
11
I
Receive and Transmit HDB3/B8ZS Enable
0 = enable HDB3 (E1)/B8ZS (T1)
1 = disable HDB3 (E1)/B8ZS (T1)
HRST
29
I
Hardware Reset. Bringing
HRST low will reset the DS21348.
JAMUX
9
I
Jitter Attenuator Mux. Controls the source for JACLK.
E1 (ETS = 0)
JAMUX
MCLK = 2.048MHz
0
T1 (ETS = 1)
MCLK = 2.048MHz
1
MCLK = 1.544MHz
0
JAS
10
I
Jitter Attenuator Select
0 = place the jitter attenuator on the receive side
1 = place the jitter attenuator on the transmit side
L0/L1/L2
7/6/5
I
Transmit LIU Waveshape Select Bits 0 and 1 [H/W Mode].
These inputs determine the waveshape of the transmitter (Table 7-1
LOOP0/
LOOP1
16/17
I
Loopback Select Bits 0 and 1 [H/W Mode]. These inputs
determine the active loopback mode (if any). See Table 2-8.
