Product Brief
MC92052
FTTC User Framer
The MC92052 is a peripheral device for the user side of an FTTC drop. It is composed of downstream and upstream
TC-sublayer functionality with UTOPIA compliant ATM-layer ports.
MC92052 Features
Implements the DAVIC short-range baseband asymmetrical physical layer standard
Supports a bit rate of up to 51.84 Mbit/sec downstream
Provides TDMA at a bit rate of up to 6.48 Mbit/s upstream, including DAVIC Bit Rates B, C, and D
Interfaces to an ATM-layer device using a UTOPIA compliant interface
Performs convolutional deinterleaving of the downstream payload blocks for the full range of interleaving depths
(M = 1-31) using an external 16K x 8 SRAM
Can optionally use an internal RAM for deinterleaving when the interleaving depth is small (M
≤
2)
Performs Reed-Solomon encoding of the upstream frames and decoding of the downstream frames
Performs HEC-based cell delineation and error correction on the downstream data
Optionally filters received ATM cells based on GFC/VPI pattern matching
Includes serial data interfaces to a Physical Medium Dependent (PMD) sublayer device
Optional serial data link interfaces for upstream and downstream frames
Includes a power level control interface to the transmitter
Provides an 8-bit system interface as a generic slave device
IEEE 1149.1 (JTAG) boundary scan test port
3.3 V operation with TTL compatibility on I/O pins
Extended temperature operation: -40 to 85
