The ACS9510 combines Semtech's SETS (TDM timing) and

ToPSync™ (PTP timing) technologies to accommodate

applications where a remote clock signal must be locked to a

central frequency source, or a clock must be aligned to a

central time source. TDM timing functionality is used for

frequency-locking applications in SDH/SONET/SyncE

equipment. ToPSync™ technology transports a reference clock

across a packet switched network without special adaptations

of switches or routers, and is ideal for carrying timing across a

legacy packet-switched network.

The ACS9510 complies with these standards:

[1] IEEE Std. 1588™ (2008).

[2] ITU-T G.812 (06/1998).

[3] ITU-T G.813 (08/1996).

[4] ITU-T G.823 (03/2000).

[5] ITU-T G.824 (03/2000).

[6] ITU-T G.8261/G.8262 (formerly G.pactiming).

[7] Telcordia GR-1244-CORE, Issue 2 (12/2000).

[8] Telcordia GR-253-CORE, Issue 3 (09/ 2000).

[9] RoHS Directive 2002/95/EC.

[10] Waste electrical and electronic equipment (WEEE) 2003.

Device features

Features

PTP Grandmaster selection - automatic or manual PTP

master/slave mode selection.

Powerful network delay analysis - delivers full time-

alignment in the slave over hostile networks (including

Layer 2 & 3 routed).

Dynamic adaptation - to network delay variations. Network

loading change tolerant (ramps and steps).

Time alignment - better than ±1 μs on a managed 5-switch

GbE network under G.8261

Frequency alignment - better than ±10 ppb on a managed

5-switch GbE network under G.8261

Programmable TDM Timing bandwidth - for wander and

jitter tracking/attenuation, 0.1 Hz to 70 Hz in 10 steps.

Automatic hit-less source switchover - on loss of input.

Output clock phase adjustment - in 6 ps steps to ±200 ns.

Precision holdover - accuracy better than 3 x 10

(manual), 7.5 x 10

defined by choice of external crystal oscillator.

Fully integrated - IEEE1588

timed solution. Integrates hardware precision

timestamping with on-the-fly insertion (no follow-up

packets required). Powerful processor and clock recovery

algorithm integrated.

Timing synchronization on a chip - supporting transitions

from legacy circuit networks to new packet technology.

Suitable applications - Stratum 3, 4E, 4, SONET Minimum

Clock (SMC) or SONET/SDH Equipment Clock (SEC) and

Ethernet, IEEE1588

Clocks - 20 clock inputs and 19 clock outputs.

Ports - MII, SPI-compatible and JTAG.

Time-of-day (ToD) - 1 PPS top-of-second signal plus

current-time-since-epoch message.

Output characteristics:

Local oscillator - operation with XO of frequency accuracy to

±20 ppm or better.

BGA package - 360 pin, 20 mm x 20 mm, 1 mm pitch.

Lead-free version - RoHS

solution for legacy and packet networks

Time-aligned output pair:

1 PPS and 125 MHz divided by n (n = 4 to 125000).

Frequency-aligned outputs:

1 Hz and programmable frequency 1 kHz to 62.5 MHz.
