Mutli-Gigabit Interconnect Chip

VSC7217

Name

I/O

Type

Pin Description

1R, 2R

1M, 2M

1J, 2J

PTXA+/-

PTXB+/-

PTXC+/-

PTXD+/-

Primary Differential Serial TX Outputs for Channel n. These pins output

serialized transmit data when PTXENn is HIGH. AC coupling is

recommended.

PECL

1F, 2F

1T, 2T

1N, 2N

1H, 2H

1E, 2E

RTXA+/-

RTXB+/-

RTXC+/-

RTXD+/-

Redundant Differential Serial TX Outputs for Channel n. These pins output

serialized transmit data when RTXENn is HIGH. AC coupling is

recommended.

PECL

TTL

PTXENA

PTXENB

PTXENC

PTXEND

Primary TX Output ENable for Channel n. PTXn+/- is active when HIGH;

when LOW, PTXn+/- is powered down and the outputs are undriven.

RTXENA

RTXENB

RTXENC

RTXEND

Redundant TX Output ENable for Channel n. RTXn+/- is active when

HIGH; when LOW, RTXn+/- is powered down and the outputs are

undriven.

18P, 19R

20U, 20V

17R, 19U

20W, 18T

RA(7:0)

RB(7:0)

RC(7:0)

RD(7:0)

Receive Data for Channel A. Synchronous to RCLKA/RCLKNA or

REFCLK as selected by RMODE(1:0).

15V, 15U

18Y, 17Y

15W, 14U

16Y, 13V

Receive Data for Channel B. Synchronous to RCLKB/RCLKNB or

REFCLK as selected by RMODE(1:0).

16C, 15C

15D, 18A

17A, 15B

14D, 16A

Receive Data for Channel C. Synchronous to RCLKC/RCLKNC or

REFCLK as selected by RMODE(1:0).

20E, 18G

17G, 19F

20C, 17F

19D, 20B

Receive Data for Channel D. Synchronous to RCLKD/RCLKND or

REFCLK as selected by RMODE(1:0).

17N

18W

17C

19H

IDLEA

IDLEB

IDLEC

IDLED

IDLE Detect for Channel n. When HIGH, an IDLE character has been

detected by the decoder and is on Rn(7:0).

When ENDEC=LOW, this is equivalent to COMDETn.

19P

16V

16D

18H

KCHA

KCHB

KCHC

KCHD

Kxx.x CHaracter Detect for Channel n. When HIGH, a special Kxx.x

character has been detected by the decoder and is on Rn(7:0).

When ENDEC=LOW, this is equivalent to data bit Rn8.
