PAGE DESCRIPTION
JP01 3-pin jumper
Pins 2+3
jumpered 10 Drives DS33R11 TDEN pin to
VCC.
JP02 3-pin jumper
Pins 2+3
jumpered 10 Drives DS33R11 RDEN pin to
VCC.
J18 Test points
Pins 9+10 and
5+6 jumpered 10
Test points, connecting RCLK and
TCLK to channel clock pins of
transceiver.
J12, J13 Test points — 11 Test points for integrated
transceiver of DS33R11.
J14, J15, J16 Jumpers Not installed 4
Installation forces Ethernet PHY
mode. When not installed the PHY
autonegotiates its settings.
DS06, DS07,
DS08 LED — 4
Activity LEDs for Ethernet PHY. Tx
lights when PHY sends a packet;
Link lights when the PHY has found
a link partner.
DS10, DS11,
DS09 LED — 4
Ethernet PHY mode LEDs. Used
for display of Speed, Duplex, and
Collision.
J21 LAN network
connection — 5 RJ45 connector for Ethernet PHY.
J22, J23 Test points — 4 Test points for MII interface
between PHY and DS33R11.
J19, J20 J24 WAN Network
Connection — 11
T1E1 coax and RJ45 connectors
for network.
J17, J25 Jumper Not installed 11 Connects adjacent coax connector
to ground.
Y03 Clock — 10
100MHz SDRAM clock for
DS33R11.

Pin bias for DS3150. When not jumpered, this pin is
pulled to ground, jumper drives pin to VCC. A basic
description of the pin function is given below. Refer
to the data sheet for full detail.
